Using 'dpkg-maintscript-helper supports rm_conffile' guards introduces
unreliability into upgrades; it means that the conffile is removed or
not depending on whether dpkg happens to be unpacked before fonts-ocr-a.
This seems generally undesirable; it would be better to enforce a single
code path. (This is academic for Debian because the version of dpkg in
squeeze supported dpkg-maintscript-helper, hence Severity: wishlist;
Ubuntu's last LTS release didn't have a sufficient version of dpkg for
that which is why I care.)
It would be nice to just use dh_installdeb's support for generating
dpkg-maintscript-helper commands, which was introduced in debhelper
8.1.0. This would remove duplicate code from your maintainer scripts -
in fact, you'd no longer need to have handwritten maintainer scripts at
all. Here's a patch:
* Use maintscript support in dh_installdeb rather than writing out
dpkg-maintscript-helper commands by hand. We now simply Pre-Depend on a
new enough version of dpkg rather than using 'dpkg-maintscript-helper
supports' guards, leading to more predictable behaviour on upgrades.
