Fair enough, this is a good argument against the shell lib
approach. It works pretty well with the conffile case, especially now
that Guillem announced it will work on it directly within dpkg.

Still, shell lib vs C implementation shows the unavoidable trade off
between being easier to deploy (shell lib) and becoming part of dpkg
itself (C implementation). *If* the goal is building a place where to
start factorizing tons of maintainer script snippets that we are
accumulating then shell lib looks, at least to me, more appropriate
and more readily available.

Don't blame me for the release notes :-), I'm culpable of not having
contributed a single line to them.

But I do agree with you, and that's actually even better. It will just
mean that if packages are fine with the current stable version of the
maintainer script helper package, fine, otherwise they will just add a
Pre-Dependency as usual. As long as the helper package maintainers are
sane-minded, we will never have pre-dep loops.
