[Pkg-fonts-devel] Bug#659716: ttf-georgewilliams: use dh_installdeb maintscript support

[Colin Watson]

Package: ttf-georgewilliams
Version: 1.0-5
Severity: wishlist
Tags: patch
User: ubuntu-devel at lists.ubuntu.com

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
ttf-georgewilliams.  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.
