Description Martin 2013-01-24 14:58:40 UTC
Description of problem:
Upgrade from clean installed F18 to F19 Rawhide.
SELinux is preventing /usr/lib/systemd/systemd-udevd from 'write' accesses on the directory watch.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that systemd-udevd should be allowed write access on the watch directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep systemd-udevd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
