[Mageia-dev] /run/httpd (maybe others) breaking features

'Twas brillig, and Pascal Terjan at 24/01/13 00:24 did gyre and gimble:

+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.
+
+> Is there a list of packages which have moved to subdirectories of /run
+> and may now be broken too?
+
+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.
