The ‘avahi-daemon’ service fails to restart these days: a stale
/run/avahi-daemon/pid upon reboot leads it to abandon. From
/var/log/messages:

The issue was uncovered by the switch to socket activation in commit
3298ec0200af0d0b0850a388df0a78e87320307f: despite using socket
activation, avahi-daemon checks for the presence of a PID file; however,
there’s no longer a cleanup process as is the case when #:log-file is
used, hence the bug.
But the core problem seems to be that ‘cleanup-service-type’ deletes
/var/run at boot but not /run. I guess it should delete /run as well?
