In-Reply-To: <20240624090850.4683-5-m.frank@proxmox.com>
This patch should probably be split into two, one adding the actual
plugin system and the second one adding the openid realm definitions -
even the patch subject suggests that it does two completely different
things.
Would also make things a bit clearer.

Should be /var/lock/pmg-realms.lck, to make it clear that it belongs to
PMG - in line with all the other lockfiles PMG creates/uses.

Can be a `my sub`, since it's not used anywhere else AFAICS, right?
