I have had a strange problem with my /tmp partition since installing FC15. /tmp is LUKS encrypted as are /home, /var/tmp, and swap. None of the other encrypted partitions have yet had the problem beside /tmp.
What has occurred twice now is some form of corruption making the directory contents un-accessible by anyone including root. Permissions are correct @ 1777 root.root, selinux policy settings fine. Only way I can find to resolve this when it happens is forced double-umount after killing all procs that are accessing /tmp, then reformatting the underlying LUKS device. Possibly related to the systemd double mounting?
I never saw this happen before a few weeks ago. Disk checks out fine also.
Anyone else know anything about this weirdness?
