Couple of Questions:

1) why was the run dir moved from /var/run to /run ? Also I noticed that the permissions will reset on a reboot for this dir if I change them (debugging ) Any other Dir's do this ?

2) I have setup a service for a compiled version of memcached (as suse doesn't provide it) and I have the PID set for /var/run/memcached which is actually /run/memcached that I created. Now on a reboot this dir disappears - what's going on ?
