I looked at [2] (cme seems really powerfull to offer automatic
upgrade/merge of config files). I've two questions after reading the wiki:
1) I vaguely recall recommendations/requirement that a package
should/must not depends on a file in /usr/share/doc/pkg for its
work (as this directory can be removed to get some place).
The wiki says that "[LCDd.conf] is now delivered in
/usr/share/doc/lcdproc and not in /etc/". Won't /usr/share/lcdproc
be a better place ?
2) "user will be asked *once* by debconf whether to use automatic
configuration upgrades or not. * no further question will be asked
(no ucf style questions)."
Why not preparing (unconditionally) the new version of the configuration
file with cmd and then use ucf to install it in /etc? That way,
the user would be prompted only when he has done new changes since
the last package upgrade (and the "install maintainer version" prompt
would then install the cme built config file)
Regards,
Vincent
