Certainly possible, but I grepped through all the systemd files
I could find with no apparent reference to avahi-daemon. I also
booted in systemd debug mode once for another problem, and
I see lots of messages about adding jobs to various lists for
startup, but no message about starting avahi in any of the
debug output, it just sorta gets started somehow all by itself.

I guess I'll have to use a bigger hammer on the grep and see
if I can find anything anywhere on the system that starts it.
