Hi Mark,

It's certainly possible insserv is renaming the shortcuts for
avahi-daemon from K02 to K01. Though this raises a few questions, I believe:

1. Why do you think avahi-daemon should be prefixed with K02 instead of
K01? (Or does it switch back and force every time insserv is run?) On my
system it is set as K01 and this looks to be correct.

2. Is there a service on the system that is getting
added/removed/changed during the apt upgrade process that is affecting
the order in which avahi-daemin is getting shutdown?

I'm suggesting it's likely insserv is making the change, I'm just not
sure if it's a bug without knowing what else is changing on the system.
