Exim spawns a new queue runner every n minutes as configured by the
argument to -q; up to queue_run_max can be active at the same time.
Spawning a queue runner only every 30 mins means that a message that
failed delivery on the first attempt (e.g. due to greylisting) will only
be retried 30 minutes later.
A queue runner will immediately exit if the queue is empty, so it is
more a function on how quickly Exim will scale to mail load and how
quickly it will retry than something that is taxing on an otherwise
empty system.
Since version 5.2.0 there's non-empty stop phase:
ExecStopPost=/usr/bin/env rm -f "/run/knot-resolver/control/%i"
but it's perfectly OK to run that from a different version
(and typically it's no-op anyway). Real-life example where this helps:

This allows to use files containing only the mpd password without the
permissions, making it easier for other programs connecting to mpd to read the
password from the same password file.
This reverts commit 8f177612b14063b644288a5a1058bf47f44b43a5.
Attempting to start any service from udev when systemd-udev-settle is
used at all hangs the boot for 2min. See issue #107341.
Since slurm-20.11.0.1 the dbd server requires slurmdbd.conf to be
in mode 600 to protect the database password. This change creates
slurmdbd.conf on-the-fly at service startup and thus avoids that
the database password ends up in the nix store.
It's very surprising that services.tor.client.enable would set
services.privoxy.enable. This violates the principle of least
astonishment, because it's Privoxy that can integrate with Tor, rather
than the other way around.
So this patch moves the Privoxy Tor integration to the Privoxy module,
and it also disables it by default. This change is documented in the
release notes.

Mailman can now work with MTAs other than Postfix. You'll have to configure
it yourself using the options in `services.mailman.settings.mta`.
This addition is reflected in the release notes for 21.03.
This partially reverts bf3d3dd19b48c432dd83aa0385b47dbe84aa647b.
I don't know why we weren't getting a default logfile back then but Xorg
definitely provides one now ($XDG_DATA_HOME for regular users and /var/log for
root, see `man Xorg`)
