Guix implements mcron, a pretty nice "new" implementation of Paul Vixie's cron. Time specifications such as @reboot are non-standard and it seems that mcron did not implement it. However, mcron comes with a Guile API. Is there some way to a command run at reboot?
Any alternative is also a solution, but it must be doable by regular users. Maybe Guix itself offers a second, off-mcron solution to the problem?
Adding the line @reboot echo hello produces the following output after crontab -e exits.
%crontab -e
mcron: /tmp/crontab.2164:1: Bad job line in Vixie file.
Edit again?
