[Bug 862129] Re: samba postrm depends on packages not guaranteed to be configured

[Robie Basak]

I discussed this bug at length with Adam on Friday afternoon. Adam is on
vacation now so I'll try and reproduce my memory and conclusions from
this conversation.

Some thoughts from that discussion:

1) perl-modules (which provides File::Temp) seems to spend a lot of time
unconfigured in the upgrade process. Adam pointed out that this is an
anomaly given how much packages depend on Perl in general, and that the
problem might be considered to be with the Perl transition and fixing
this may be one approach. Take a look at VarLogDistupgradeTermlog.gz in
bug 856309 for example - perl and perl-modules are unpacked but not
configured in the entire session. I understand that this still complies
with policy; the way I see the problem is that perl-modules and update-
inetd still need to export some kind of mechanism to make them usable
within maintainer scripts for them to be useful.

2) If update-inetd is supposed to be able to be used from within
maintainer scripts, what is the correct way of doing so? If it is
supposed to be used from a postrm and thus cannot rely on perl-modules
to be configured, then is the bug really that update-inetd is depending
on things that it cannot?

3) If we could change update-inetd to not depend on Perl modules that
may not be configured, then this particular bug wouldn't be an issue any
more. It looks like we may only need tempfile anyway, which is in
debianutils and Essential. The advantage of File::Temp seems to be
portability, which isn't an issue for us as we guarantee tempfile to
always be available. update-inetd also appears to need File::Copy so
I'll need to check this, but in any case would the approach of removing
dependencies by bringing minimal implementations into update-inetd be
acceptable?
