-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Package: anacron Version: 2.3-20 Severity: normal Tags: patch
I now have anacron maintain btrfs volume scrubbing, which blocks all
other jobs when it runs. I use anacron precisely because it should run
the jobs it manages in parallel (theres cron.daily/weekly/monthly via
run-parts for serial jobs) - reading the manpage confirms this intent:
=======================================================================
Unless the -s or -n options are given, Anacron starts jobs immediately
when their delay is over. The execution of different jobs is
completely independent
=======================================================================
Debian's '/etc/init.d/anacron' script indeed hobbles this by calling
anacron with '-s'. I have attached a patch to allow anacron's
arguments to be user-customisable in the '/etc/default/anacron' file -
the patch keeps the current configuration.
Thanks
