[pve-devel] [PATCH manager 1/4] add tpmfiles.d config to create /run/pve directory

[Fiona Ebner]

The pve-lxc-syscalld systemd service currently uses /run/pve as a
runtime directory. This means, that when the service is restarted, the
directory will be recreated. But the /run/pve directory is not just
used as the runtime directory of this service, but also for other
things, e.g. storage tunnel and mtunnel sockets, container stderr logs
as well as pull metric cache and lock, which will be lost when the
service is restarted.

The plan is to give the service its own runtime directory that is only
used for that purpose and nothing else. However, this means the
/run/pve directory will not get created automatically anymore (e.g.
pull metric relies on the existence already). Add this tmpfiles.d
configuration to create it automatically again. Note that the
permissions/owner are different now. As the runtime directory, it was
created with 0755 root:root. This tmpfiles.conf configuration
aligns the permissions/owner with the ones /run/pve-cluster has, i.e.
0750 root:www-data.

We could also opt for 0750 root:root, not sure.
