| | This patch adds a new "--disable-version-links" configuration option
that allows installing to the standard GNU installation directories
instead of having to add symlinks in /etc/ganeti/{lib,share} that
points to the right $ganeti/{lib,share}/$version. Mainly to reduce
service complexity, and because Guix users can install as many versions
of Ganeti they can muster without resorting to such hacks.
