[PATCH 1/8] pakfire: Automatically compose $version

[Michael Tremer <michael.tremer@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1948 bytes --]

The tree in which pakfire is looking for packages and Core Updates
has been hardcoded into /opt/pakfire/etc/pakfire.conf.

This patch adds a new function which reads the system release
from /etc/system-release.
