[pve-devel] [PATCH v3 container 2/2] vzdump: move include logic for mountpoints to method

[Aaron Lauterer]

Move the logic which mountpoints are included in the backup job to its
own method and adapt the VZDump code accordingly. This makes it possible
to develop other features around backup jobs.

v2 -> v3: rebased

v1 -> v2: implemented the suggestion from Fabian [0]
