(Don't worry, it probably won't happen). Thanks for tipping in! In light of this, it seems it'd be a better option to add crond support at the level of Guix Home, which would allow easily configuring mcrond as a user service rather than at the system level. Thanks, Maxim

Dear Ludo=E2=80=99,
I haven't forgot about this issue. Writing simple service isn't a
problem, but I've found out that despite running cron daemon, crontab
doesn't notice it. I've reported that behaviour on mcron mailing
list[1].
Second issue that I haven't figured out yet is creating crontab file for
each user of the system upon cron service activation. It needs
/var/cron/tabs to be owned by root: and crontab for each user to be
owned by him, ideally by (for example) user1:user1.=20
