Hi,

While debugging an unrelated reproducibility issue with an older mtools
version I got the idea of testing packages that uses mtools (with the
current Guix version) and it turn out not to be reproductible:
 $ guix challenge syslinux

Here's my Guix version:

I'm unsure if it has the same issue I'm struggling with or not (FAT12
and maybe FAT32 as well store last access date (without the time) so
it's easy to mess up testing).

Denis.
