MySQL wont work out of the box, says it can't create/write pid file.
Played around with it, couldn't find the source of its problems.
ps There is no mysql component to put this ticket under :)
MySQL (running as user mysql) has no permission to write in /var/run.
This is a known issue and we're working on a errata release.
As a temporary work-around make /var/lib/mysql readable.
