Hmm, not sure what you mean here.

[colin at mga2 ~]$ ls -ld /var/run
drwxr-xr-x 38 root root 4096 Jan 23 04:04 /var/run/

That dir is also owned by root with 755 perm. It shouldn't make any odds
to permissions.

Again I don't think so. The fact that /var/run is just a symlink now
should be irrelevant.

Also the fact that /run is mounted on tmpfs vs real fs again should not
alter permissions in any way - all it really means is that

a) it'll be cleared at boot
b) we have to create files/folders with appropriate ownership/perms
during early boot via tmpfiles.

So I'm not really sure what you're saying here, but I don't think it is
any more broken now than it would have been before using /var/run directly.
