Description Michael S. Tsirkin 2012-06-20 12:12:39 UTC
Description of problem:
I edited /etc/sysconfig/network and modified the host name.
X was running.
At this point I got these errors from selinux:

Comment 1 Daniel Walsh 2012-06-20 19:13:46 UTC
Remove firstboot_tmp_t directories, so this should just work without generating avc's in the future.

Fixed in selinux-policy-3.10.0-133.fc17
