[pve-devel] [PATCH manager 10/15] postinst: simplify code for transitional updates

[Thomas Lamprecht]

The first case won't happen anymore on a recent PVE.
The 'version is empty or <unknown>' check may drop the '<unknown>'
part, it gets handled by the 'dpkg --compare-versions' bits just
fine, if it happens at all for the 'configure' case
