Not only every upgrade, but if I'm reading the report correctly it looks
like insserv is toggling between K01 and K02 with every time it is run,
even if no "apt upgrade" happens. Assuming I'm reading that report
correctly that means insserv is giving different output from the same
input every time.

I've tried this on my own machine with avahi-daemon installed and I'm
not seeing the same thing, in my case it always gets assigned to
K01avahi-daemon.

Something that might be useful here is seeing the output from "insserv
-v -s -n". This will show in what order insserv intends to assign each
service in each runlevel. No changes will be made to the system when
insserv is run with the "-n" flag.

It might also be useful to have the LSB header from the avahi-daemon
service file in /etc/init.d/
