I'd like both but little endian has the widest eco-system support especially w.r.t. to Linux drivers. Many Linux drivers have endianness bugs (lack of endian-safe serialization for DMA..), it's such a plague that sticking to little endian is just better right now.

I suppose it would be possible to downgrade glibc in bootstrap.scm, but I wouldn't count on maintaining a separate glibc for powerpc64le vs the rest of the architectures.

As far as powerpc64 vs powerpc64le, I'll let those with the hardware have more of a say, they'll be the ones using it. As far as the bootstrap binaries go, I don't remember having this much pushback with my binaries for aarch64 (just a request to rebuild with guile-2.0.14 since it was reproducible), and I'm not sure how much Janneke had with the Hurd binaries but I don't think it was this much. The ultimate goal anyway is to replace them with artisanally crafted mes binaries, and I understand we want to have them as reproducible as possible, but I don't think it's fair to keep this architecture out when we've let other ones in with similar reproducible problems. --=20 Efraim Flashner <efraim@HIDDEN> =D7=90=D7=A4=D7=A8=D7=99=D7=9D = =D7=A4=D7=9C=D7=A9=D7=A0=D7=A8 GPG key =3D A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted --JRM4f1yYltQp8k+u Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEoov0DD5VE3JmLRT3Qarn3Mo9g1EFAl/XH40ACgkQQarn3Mo9 g1F2OQ/+IhXOhx+T/vTIGuINNrtMsoKqdHdGDlzxZOpaLVp7mp/vb/O8S5EPsHD+ yryb8CuSo5FktYZ/qbRHLIO9TgKKzZe08nklB1ZZQTP1ZUFwwrHvBIbntWk1JQUm s8/slZwZyZBOp/NjjM5+7ypBiW7ml2pA1vLVHvyrWoDCc2n5r1p1T0t2rwwUSbRO zAzTzArMVHyWWeugzbB8MsjMLzSJquyZsyznB4yY31s+e8Kv6+pL+W+3u80bcfp0 h9BWS2fqvtck1vjVQu6T1KNyqbgGJicjqwpt+y6vJpIhxR7Lltg346saJxqmzOHy zTKHFZJBkmKF9N3PSGlif2DHyuK/QtXT1GxMcCgvoThrzt+mx9JNm6MP8eVWGu5f Typ/3ncskStf+ybf2n+vmV4FDMDwT9KhB+N3W1zo54jSC9hZ3LWHXfK11jnzhhyb L50SbyokTVwqhGZOrtvgh3el9Zgzg0+scJikjvHYIoJppX8m3M+QX6vCwhXFqpFa +UuZobypZwr2G+AGZk4EiUWUEDSdfXaFtnmOfXHMXj9D0Uyl/i4+DXDKNOMnburk XD6HlRv5C+Ncb/c5AuOjZXtjt1vL2+929+Jt1T+4DIEqMQxBJe8RQdsRtGOTOWLT Twn0lmkK/miuls1sMKmYqzkHmshvn8gG1ynvQr6TuCYkFR/lk2w= =6SXH -----END PGP SIGNATURE----- --JRM4f1yYltQp8k+u--

Hi,
I tried to do some experiments to see if this problem happens with the
current GCC (version 10).
I built GCC 10 (not cross-compiling) on an x86_64 system using Guix with
substitutes on Debian. (I tried without substitutes, too, but some of
the dependencies failed to be built for unrelated reasons.) I then
manually copied the /gnu/store and related files (except for the GCC 10
output paths) from Debian onto a Fedora machine, and I rebuilt GCC 10
there using Guix (again, not cross-compiling). The output on Fedora was
identical to that of Debian. Of course, the configuration Guix uses to
build GCC 10 is a bit different from the one used to (cross-)build the
powerpc64-linux bootstrap GCC, but it's still an interesting data point.
In particular, GCC 10's libstdc++.a was identical on Debian and Fedora,
so I suppose maybe they've fixed that issue in the more recent versions.
I also tried to use Guix (the current version, from master branch - I
ran guix pull today) to cross-build gcc-10 for the powerpc64-linux-gnu
target on both Debian and Fedora x86_64 systems, starting from scratch
with substitutes enabled:
guix build --target=3Dpowerpc64-linux-gnu -e '(@ (gnu packages gcc) gcc-10)'
On both Debian and Fedora, the build of gcc-10.2.0.drv failed with the
following error:
checking for -fPIC -shared... yes
configure: error:=20
Building GCC with plugin support requires a host that supports
-fPIC, -shared, -ldl and -rdynamic.
This basically just means that we can't cross-build gcc-10 for
powerpc64-linux-gnu out of the box on x86_64 with current Guix. I was
hoping that the builds would succeed, and I would be able to find out if
cross-building gcc-10 in this way would create non-reproducible
artifacts. I was hoping maybe I could ask for help from the GCC
community if that were the case. But since it doesn't even build, the
results of that experiment were not very useful.
It's been almost half a year now, and we're not really any closer to
figuring out why the cross-built GCC bootstrap binary is
non-reproducible. It seems counter-productive to obsess about making
this specific binary reproducible, although I wish it could be so.
What do you think about using the bootstrap binaries we built half a
year ago, and proceed with bootstrapping efforts? To be totally honest,
I'm feeling pretty exhausted by this bug, since I have spent so many
days trying to unravel it, and I haven't made any significant progress.
With no clear end in sight, I would really prefer to move on instead of
blocking the entire bootstrapping effort on this reproducibility bug.
The reproducibility of the bootstrap binaries is important, but simply
having any bootstrap binaries at all is also important. I think I have
done my due diligence to try making them reproducible. Most of them
are, but I just can't figure out why GCC isn't. I think it would be
best to proceed with the binaries we have.

Actually, --disable-shared is already present in the configure options.
My understanding is that libstdc++.a is a statically linked library
(perhaps I am mistaken...?), so I don't see why the presence or absence
of --disable-shared would affect it. I thought that option was just
supposed to control whether or not to build shared libraries.

I've spent all of my spare Guix time trying to debug this
reproducibility issue first, and half a year has passed without progress
as a result. I think we should use the bootstrap binaries we built half
a year ago, and move on with life.
At this point, it might even make more sense to try bootstrapping for
powerpc64le instead of powerpc64, since the rest of the world seems to
be gravitating toward the little-endian variant on POWER9 hardware, and
thus various programs out there are more likely to be better tested on
powerpc64le than powerpc64.
In any case, I don't think we should wait any longer.

Hi everyone,

That's a good idea. I tried building %gcc-static with the
=2D-disable-libstdcxx configure flag (see attached patch), and that caused
the build of %gcc-static itself to become reproducible on Debian and
Fedora when using exactly the same inputs. To clarify, I have recently
run the following experiments:
+------+-------------+---------------------+--------------+----------------=
+---------------+
| Case | Build | libstdcxx | substitutes? | Inputs =
| Result |
+------+-------------+---------------------+--------------+----------------=
+---------------+
| | | | | Built fresh on =
| Output |
| 1 | %gcc-static | enabled | yes | Debian, copied =
| differs: |
| | | | | to Fedora =
| libstdc++.a |
+------+-------------+---------------------+--------------+----------------=
+---------------+
| | | | | Re-used inputs =
| Toy binary |
| 2 | toy program | n/a | yes | from above =
| does not |
| | | | | =
| differ |
+------+-------------+---------------------+--------------+----------------=
+---------------+
| | | | | Built fresh on =
| Output does |
| 3 | %gcc-static | disabled | yes | Debian, copied =
| not differ |
| | | | | to Fedora =
| |
+------+-------------+---------------------+--------------+----------------=
+---------------+
| | | | | Built fresh on =
| Output |
| 4 | %gcc-static | disabled | yes | Debian, fresh =
| differs: |
| | | | | on Fedora =
| various files |
+------+-------------+---------------------+--------------+----------------=
+---------------+
| | | | | Inputs failed =
| Build failed |
| 5 | %gcc-static | disabled | no | to build on =
| on both |
| | | | | both systems =
| systems |
+------+-------------+---------------------+--------------+----------------=
+---------------+
The "toy program" in case 2 was just this:
#include <stdio.h>
int main() {
printf("Hello");
return 0;
}
When I say I "copied" the inputs from Debian to Fedora, I mean just
that. I copied stuff like /gnu and /var/guix from Debian to Fedora
(while guix-daemon was stopped, of course), GC'd just %gcc-static on
Fedora, and then rebuilt %gcc-static on Fedora so it would use exactly
the same inputs as were used on Debian.
The most notable new findings are cases 3 and 4. Case 5 made me pretty
sad because I spent almost an entire weekend trying to build Guix from
source using various binary Guix releases, and in none of the attempts
was I successful in running "guix pull" or even just "guix environment
=2D-pure guix" without substitutes, which really surprised me.
Case 3 confirms Efraim's suggestion: we can fix the libstdc++.a
reproducibility problem by simply not building libstdc++.a in the first
place. It also confirms that, when built with --disable-libstdcxx,
%gcc-static can be built reproducibly on different systems as long as
exactly the same inputs are used. Whether or not %gcc-static can be
used to successfully bootstrap packages on powerpc64-linux when built in
this way remains to be seen.
Case 4, unfortunately, demonstrates that there are still other
reproducibility issues that we have not yet resolved. Since the only
difference between cases 3 and 4 is how the inputs were realized, the
differing %gcc-static output must be caused by the inputs somehow.
In case 4, the %gcc-static output differed in the following files (the
hashes on the left are MD5 hashes):

These appear to be the same diffs that I reported before - with the
notable exception that libstdc++.a now is missing from the list of
differing files (hooray!).
Going forward, I'm not sure how best to investigate the inputs to find
out what's causing the differences. I just know I really, really,
really don't want to rebuild everything multiple times, since it takes
hours/days. If you have any creative ideas for how to speed up the
investigation, I'm all ears.

After further experimentation, I've discovered that %gcc-static, when built as shown above (without the -d option, of course), produces different output on Debian than on Fedora. Specifically, the %gcc-static output contains a file named libstdc++.a. This file is an archive file. Although its members are content-identical in the case of Fedora and Debian, the order of the members in the archive differs. Because the exact same inputs were used, it seems very likely that a difference in the Guix build environment caused the %gcc-static build logic to order the members of libstdc++.a differently. I built %gcc-static using Guix commit a02b2f8b86c0227eb69aa24b4373aef456365334. Both Debian and Fedora were x86_64-linux systems.

The %gcc-static package uses GCC 5.5.0 as its source. I got a copy of the GCC 5.5.0 source code, and I looked at it. However, it's complex. I can't pinpoint where they actually build the libstdc++.a file. Can anyone point me to the code that does this in the GCC 5.5.0 source? I expected to find the logic hiding in a makefile or a configure script or something, but I haven't found it yet. Since this is an old GCC, it is possible that this was a known reproducibility bug which has since been fixed. I haven't looked into that possibility yet. If that's the case, though, it would be nice because we could simply backport a fix. =2D-=20 Chris --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEy/WXVcvn5+/vGD+x3UCaFdgiRp0FAl9diZAACgkQ3UCaFdgi Rp0WHxAAxQnPB0Dg4GfaXrtRxOwZsqVuNlg14Qpp46YzroCJ66MyK3x4ddekFIkj p1pyyzLVF9RSvsPspf9oc0Go12JndQMOqpsAUE0rJLbVPbTlrNrkh9Jhhfar95IX p+cSNQoeuab1+nOeUH17J2TMdoxsXiwzB/4IuQHQtNLe3DVNKmIYB0tgL/L/Xasc WN0qHyNwkW/Lobs4jWNzukD3DiCv+zN0r1eDwsk02EOegW+m5yeyGMKbQUa7QCba g5vGeSi92AiqEVkuj62/IObMFVQP1rlNUBN9a3Yn8UTxW//PF9fwkJRIpSqdmGx7 VYpRJ/e4L6NT2GE91X+RPz0Pz0J9viV/lsM8esALudxQRv2/1loh4T6mubM394Cw yrhv2TxFmtlrBAEGJmIulCSOKGTJYy2bXbq2vR0sfbXZs3iKvPdY0FVyy3NShTz0 d3+Yk1T1dXw0tKQBmr04mpq+2SFvKTrHJB3FmVQa8/v+q+Q7ca10/X7NhcIgMG5H Nq7ttes7zV/zlIvWRChCKUHyefQBzN00ZQeBWfsJykko4m6W5vquOVs0Log54TrJ rgQIZAickNIQSMcG0fOVmzaj7iGf1smiaeB3bIW91Ub6FJ9NuoJuyLMFd6xmezVJ gv3wpnd6Yh9kzORQV79C14iIDUvYIOPJn3qBm1DPe5RQdlu3wn4= =OFt6 -----END PGP SIGNATURE----- --=-=-=--

Can you clarify what you mean? I'm not sure what you're referring to.

I repeated the experiment on the same machine (it took a day or two to
build), and the result was the same: on my machine,
gcc-stripped-tarball-5.5.0.drv builds identical output to what it built
before. To be clear, using Guix 8159ce1970d91567468cf1bacac313099a009d2a
on an x86_64-linux machine, I tried (yet again) the following steps:
=2D I deleted as much as I could from the store using 'guix gc'.
=2D I explicitly verified that all outputs for the following derivations
no longer existed in the store:
/gnu/store/pygln3lr6qbxcps3kmn3w4bc0d0nlpd3-gcc-stripped-tarball-5.5.0.drv
/gnu/store/kcv3ja1rfr93hw6ly51878zjhdwpgv7z-gcc-stripped-5.5.0.drv
/gnu/store/m9hfwppla8lph0vxa15lfkp81s2bbjjs-gcc-static-5.5.0.drv
/gnu/store/g9fpkg2qa27mka1znqsvx8vxqyabsj2y-gcc-7.5.0.drv
=2D I then built gcc-stripped-tarball-5.5.0.drv via the following command:
guix build --no-substitutes --check --target=3Dpowerpc64-linux-gnu \
-e '(@@ (gnu packages make-bootstrap) %gcc-static)'
This rebuilt basically everything, including gcc-7.5.0.drv and the other
derivations mentioned above. When I checked the built output of the
gcc-stripped-tarball-5.5.0.drv derivation, I found that its SHA-512 hash
was identical to the one I calculated previously, which was:

Anyway, this confirms what we already knew: GCC builds reproducibly on
my machine, but it is different when other people build it on other
machines. I'm now quite convinced of this fact.
Jack and Vincent shared their build results on the email list. For
reference, you can get them here:
https://flashner.co.il/~efraim/gcc-stripped-5.5.0-powerpc64-linux-gnu.tar.xz
https://jackhill.us/misc/gcc-stripped-5.5.0-powerpc64-linux-gnu.tar.xz
https://media.marusich.info/gcc-stripped-5.5.0-powerpc64-linux-gnu.tar.xz
I also received a copy of Vincent's build results via private email. In
short, they all seem to differ in basically the same ways:

Efraim's diff looks a little different in statx.h, even though he used
the same Guix commit as me. Maybe this is because he cross-compiled on
an aarch64-linux machine, while I cross-compiled on an x86_64-linux
machine. In the other cases, it looks like the binary files differ in
basically the same ways. I will share some examples below.
Here is some diffoscope output between my c++ and Efraim's (many other
sections also differed in similarly cryptic ways):

If I'm reading this correctly, one problem seems to be that our GCC
toolchains are putting symbols at different locations. This issue (and
maybe others) could be trickling down, causing other aspects of the
binaries to differ (e.g., in length). Nothing really stands out, but
when we discussed this on IRC, we thought perhaps factors like the
following might contribute to the non-reproducibility:
=2D Perhaps we are all running different Linux kernel versions? In some
cases, the kernel version can unfortunately influence the build
output, so this might be worth testing.
=2D Perhaps the GCC Makefiles etc. are doing something non-deterministic?
=2D Something else?
Avenues of investigation:
=2D If anything obvious stands out from the diffoscope output, please
leave a comment.
=2D Try building with different kernel versions on the same machine, to
see if they differ.
=2D If somebody else could please confirm that running the following
command reports no difference on their own machine (i.e., exit code
0), that would be good to know, since it would help further solidify
the theory that on a single machine, the build of gcc-static-5.5.0.drv
is reproducible, even if it is not reproducible across machines:
guix build --no-substitutes --check --target=3Dpowerpc64-linux-gnu \
-e '(@@ (gnu packages make-bootstrap) %gcc-static)'
=2D Try building two different versions of gcc-7.5.0 (maybe by hand?), and
then use them to build a simple reproduction case and compare results.
If we're lucky, maybe this will help us understand the problem better.
We'll get there!
=2D-=20

This derivation corresponds to %gcc-bootstrap-tarball from (gnu packages make-bootstrap), which just creates a tarball of the output of %gcc-stripped. Therefore, it's not too surprising that it's reproducible. Similarly, %gcc-stripped just strips some store references from the output of %gcc-static. The %gcc-static package is more interesting: it's where we actually build the statically linked bootstrap GCC (which is then stripped and packed into a tarball as mentioned above), so I thought that it might be where the non-determinism is coming from. However, I haven't yet pinpointed the problem. If you examine the derivations and their inputs, you'll find that they depend upon each other in the following order: guix build --target=3Dpowerpc64-linux-gnu -d -e '(@ (gnu packages make-boot= strap) %gcc-bootstrap-tarball)' /gnu/store/pygln3lr6qbxcps3kmn3w4bc0d0nlpd3-gcc-stripped-tarball-5.5.0.drv guix build --target=3Dpowerpc64-linux-gnu -d -e '(@@ (gnu packages make-boo= tstrap) %gcc-stripped)' /gnu/store/kcv3ja1rfr93hw6ly51878zjhdwpgv7z-gcc-stripped-5.5.0.drv guix build --target=3Dpowerpc64-linux-gnu -d -e '(@@ (gnu packages make-boo= tstrap) %gcc-static)' /gnu/store/m9hfwppla8lph0vxa15lfkp81s2bbjjs-gcc-static-5.5.0.drv In other words, gcc-static-5.5.0.drv is an input of gcc-stripped-5.5.0.drv, which is an input of gcc-stripped-tarball-5.5.0.drv. Above, I've included example guix commands you can use to obtain each derivation. Using "guix build =2D-check", I confirmed that all three of these derivations build reproducibly on my machine. I hoped to find more information by invoking "guix build --check" on every input of gcc-static-5.5.0.drv. When I tried that, what I found was that all of its inputs build reproducibly except the following two: /gnu/store/x32cnfkd50fnxs10xp1jdn24h7ai2gxr-guile-3.0.2.drv /gnu/store/g9fpkg2qa27mka1znqsvx8vxqyabsj2y-gcc-7.5.0.drv I haven't investigated guile-3.0.2.drv. However, gcc-7.5.0.drv felt more suspicious to me, and it is actually the derivation that builds gcc-final from (gnu packages commencement), which you can see via: guix build -d -e '(@@ (gnu packages commencement) gcc-final)' Using "guix gc", I deleted the outputs of gcc-stripped-tarball-5.5.0.drv, gcc-stripped-5.5.0.drv, gcc-static-5.5.0.drv, and gcc-7.5.0.drv. I then tried building these four derivations again (without substitutes, the same as before). Before doing this, I stored the SHA-512 hashes of their output files, and after the build succeeded, I compared the hashes of the new files with the previous values. I found that these derivations' newly rebuilt outputs were identical to their original values, except for gcc-7.5.0.drv, which produced some different files. Most significantly, this means that gcc-stripped-tarball-5.5.0.drv produced the exact same tarball for me as it did the first time I built it, even though some of its inputs are not themselves reproducible. At present, it seems possible that within the context of a single machine, gcc-stripped-tarball-5.5.0.drv builds reproducibly, but on a different machine, it may (reproducibly) build a different output. I'm a bit paranoid about making mistakes, so I'll perform another full GC and then try yet again to build gcc-stripped-tarball-5.5.0.drv in order to verify whether it truly produces the same output when all (or nearly all) of its inputs are rebuilt from scratch. Some people have also shared their differing copies of the binaries on the email list. It could be productive to compare the contents with diffoscope, although I suspect the diff might be too large to be useful. =2D-=20 Chris --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEy/WXVcvn5+/vGD+x3UCaFdgiRp0FAl7XceUACgkQ3UCaFdgi Rp0EgRAA0OmlaDC8TFlxSXsGjlbPVhV5kO7mplWnYNAbROMWrFWoRU4okIISdCeV pklnsneNtg9UN+OagjGMNsgw6w/iaiftMduLS17AqWeUoaCi7HUTGVgwg6AZD2z3 nWFFgjPdYy8NO0uSA4wxoqGXHIXZsmy6m8HlNkQ5Wxv4ILrMLW1aAloAwLuicnD7 xszXKVfC38UyVwdjVyTbdVqUcl8QPY8jYdQtk+RtK6Yb1aWba6xyFW6FZhgNl4PW DcEIBD6lKewXYT8saDJkkD1dBhkGiHjMPWkDPKiDuPR7dfDhrm4QHxRZHifv5Fu3 wGoya2yxyCtaB2O/xH8YLiQiLbWjGE+pZdbGN3hIwf8ie2lilK97895hTIhMRasi 1q6XMpRW27X8cZG7nv/spMyo3Zu/PudOghzOk/h16W0Ey24hLv0IO4xAtUxCprnB 4gtU/hKxbKYS8mN4K9AmkgnCDlibfAuEqRAwAcDpA3oxobjZLTih/BBlulUn3pxN lf4/xIn9DCaZpi9pckjYnucByP0wv/JjA4aJGBpPM9rfau805E8XeHtBBX1djsL0 ekPaT9BkEYVxILT9eHkrIp3JO5P1H0dRqhtT6XUFShKwe9FC3BgxaJeW8v7DsLnv bsKJ/0nXMjrcjJBqR5FhuAy/ZZXi+ILivSHQ5QlG/D1uBg8kEPM= =kMiK -----END PGP SIGNATURE----- --=-=-=--

However, these attempts produced four different versions of gcc-stripped-5.5.0-powerpc64-linux-gnu.tar.xz. At least two of the attempts were performed on two different x86_64-linux systems. The derivation that produced the differing output was: /gnu/store/pygln3lr6qbxcps3kmn3w4bc0d0nlpd3-gcc-stripped-tarball-5.5.0.drv You can build this derivation in a variety of ways, for example: guix build --target=3Dpowerpc64-linux-gnu -e '(@ (gnu packages make-boots= trap) %gcc-bootstrap-tarball)' or just guix build /gnu/store/pygln3lr6qbxcps3kmn3w4bc0d0nlpd3-gcc-stripped-tarba= ll-5.5.0.drv On my x86_64-linux system, twice I tried running "guix build --check" on this derivation, but each time it surprisingly reported no difference. Out of paranoia, I tried deleting its output with "guix gc --delete", and then building it again. The new output was, indeed, identical to the old output. This makes me think that the non-reproducibility is coming from something outside the immediate build logic of the gcc-stripped-tarball-5.5.0.drv derivation itself. I will next try to rebuild everything from scratch again. I will also try to get copies of the differing outputs from the people involved in that email thread, in order to run diffoscope on them. =2D-=20 Chris --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEy/WXVcvn5+/vGD+x3UCaFdgiRp0FAl7WoXcACgkQ3UCaFdgi Rp0twQ//VDfFrWpdAkX4XpGke8c4sT6/W2LbR7N+xl126nbXhcAKjH13SCjgX3vp /Yrik1IlnEhXwPpujU6GXLv7UbjZLBDERMOee0bFpreaq9TQMq2NJQkcoKE4kOSr +ockDEE71tv4ZEjW3hY8funw9uRGoZBcyPYHyIjd0bNYvRAa1x8nuhrXYE5+rRZ2 h/2k5tynQrkMpxUEVQr0XL0OWXhY5VPD9Wwgd3anY/l643RIg2eLTDF1kvnRCdOq OFN+88hWEx3QzPMZ852SSc99XkHRBaboFkrNIquxIU2lsOHiUSwOkT4/NrdOoeW7 +pXgJ2dcUNvI1JHER50NUjHBndqCke1bYUbCll0f9VE7hi1z/V/hut4t7a5uTUXp QP+aLeS9WDDDyFHwYPf6hotjNwCyOE1aBo0LlNpR+nIX4WSDYCzSKIFQFAva84l2 TDRte0rIKcZ/B3xRraGjgFwJBezme8RkOiORNzFpcRzf0y5hCSPvL3cLc8XmsbAl HT8pCdm0b3kSlBNQmUSV+XxnXvpIUDnxernYb7PEYhgWsopyHBgQtfxMqCj/IZtE OXeh/oumsuKZWxDcgbUI81liQPNlrFlXgfsWiUmtBmv56g/jFko+e+IgIIZroGWj iWHVBGz1EMaENBMXpga4g7XMRTXoXO3QB9xGQ34mHsZC007QPwQ= =DG+o -----END PGP SIGNATURE----- --=-=-=--
