Yeah, that I noticed later too, but it would be indeed good to check if
this is a guarantee (i.e., by Debian policy) for all systems now, even
if they got created with a very ancient PVE/Debian version.

I only did a quick check, and found [0]:

So does not seem like a hard guarantee that /var/lock is always a symlink
to /run/lock and that /var/run is always a symlink to /run, so if the
careful approach would be to switch to the new paths for our Trixie based
builds and add a check for the case where /var/lock and /var/run are not
symlinks in the future pve8to9 checker script and output a warning/error
in that case; that said I'm not sure if it's worth it, would be maybe good
to see since which Debian/PVE version the symlink exists to be able to
better judge that though.
