[Bug-mcron] mcron in a multi-user setup

[Ludovic Courtès]

Hi,

I’m looking at providing a service definition in GNU Guix for mcron.
The problem is that mcron seems to assume a single user.  I’ve used it
that way, running it with my user account privileges, and this is fine.

However, it would be convenient if we were able to run a single mcron
process, presumably as root, and a command akin to ‘crontab’ to force
mcron to reload user files.  WDYT?

Also, the ‘crontab’ command currently fails with:

  ERROR: Unbound variable: crontab-user

Lastly, the manual mentions ‘at’ commands.  It would be perfect if these
were actually provided.  :-)

Thanks,
Ludo’.
