Leaving the configuration during reinstallation package

[ghost]

When you install/update/remove or change the package, eg. reinstall minidlna to minidlna-rescan, existing configuration file (minidlna.conf) is overwritten/removed. Can not you leave it unchanged, and the new, the original configuration file from package set as for example minidlna.conf.ipkg?

This can be done, however, this requires doing this manually for every package with config(s). I like the way it's done by Debian dpkg: configs aren't deleted unless manually requested to (when purging). Unfortunately, though, I'm not familiar with ipkg code, so it's too much work for me to implement such approach.

A possible, easier way is, as the official minidlna debian package does, using /etc/default/minidlna

for minidlna's future release package, in init script (i.e., S98minidlna), just after

test -x $DAEMON || exit 0

add

# Read configuration variable file if it is present
[ -r /opt/etc/default/minidlna ] && . /opt/etc/default/minidlna

When user installs this new package, his /opt/etc/minidlna.conf will still be replaced by the new package.

However, the user can create /opt/etc/default/minidlna with

DAEMON_OPTS="-f ${prefix}/etc/myminidlna.conf"

and S98minidlna will start minidlna using user's own configuration file (/opt/etc/myminidlna.conf), that file will never be modified by the new package.

Of course, user is responsible for merging changes in minidlna.conf from the new package.

I believe this is now fixed in latest ipkg-static version:

ipkg-static is based on opkg 0.2.4, with some OpenWRT patches, and a patch to use ipkg pathes for backward compatibility (installed packages data stored in /opt/lib/ipkg, and /opt/etc/ipkg dir scanned for configs), and opkg 0.2.4 clearly supports this.
