[pve-devel] [PATCH container v2 2/4] fix os-release mapping for similar flavoured distros

[Thomas Lamprecht]

This avoid failing the check where the auto detected type differs
from the configs ostype.

changes v1 -> v2:
* replace regex with simple checks to already available info, this moves the
  fixup into "autodetect_type" where it fits better
* warn not die on the check, dying here does not gains anything for the user
  - Inform him that something maybe wrong. Allows situtations where a user
    wants a unmanaged CT but autodetect_type would still detect a known one
    in it.
