[bug#74860] [PATCH 00/10] Using the Shepherd's log rotation service

["Ludovic Courtès" <ludo@gnu.org>]

Hello Guix!

Shepherd 1.0 provides a bunch of new features, but now we need to
bring them to Guix System and Guix Home.

This patch series focusing on log rotation: (1) using the Shepherd's
log rotation service, (2) getting rid of Rottlog usage and deprecating
it, and (3) adding log rotation for Home.

Since ‘log-rotation’ only exists in version 1.0 of the Shepherd,
reconfiguring a system that runs an older version of shepherd will
warn that “some services could not be upgraded and reboot may be
needed”.  If the user chooses not to reboot right away, there are
several possibilities:

  • If the mcron service was not unloaded and is still running,
    it will run rottlog as before, that’s fine.

  • If the mcron service was not unloaded, but the user ran
    ‘herd restart mcron’, the new mcron will not have Rottlog
    among its jobs, so log rotation will no longer happen until
    reboot.

  • If the mcron service was unloaded (because nothing else in
    the new system config needed it), then log rotation will no
    longer happen until reboot.

To sum up: worst that can happen is that log rotation stops until
the system is rebooted.  (Of course everything is fine if the
machine already runs Shepherd 1.0.)

That seems acceptable to me, though I guess we can wait for two
weeks before pushing this so more people have upgraded to 1.0.

Thoughts?

Ludo’.
