Package: fonts-f500
Version: 1.0-3
Severity: wishlist

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-f500.
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.
