Code review comment for lp:~racb/ubuntu/oneiric/samba/862129

The effect of this change is to make the system non-deterministic. If
we want update-inetd to work from postrm scripts, don't we instead need
to make sure that it always works even if unconfigured, as if it were an
Essential package? This would be much safer and the resulting system
would be easier to understand.

I'm also unconvinced about the reliability of the data returned by
dpkg-query from a maintainer script. It may be better now, but
historically this didn't reliably reflect the state of a running dpkg
instance.

To be honest, I think there are too many questions about this kind of
thing for it to be safe to attempt a fix for this for oneiric. I'd
rather we got it right in precise, and then maybe backported the fix.
