Description Kamil Páral 2014-10-27 16:34:14 UTC 
Description of problem:
I received this at the end of anaconda installation when debugging bug 1157657.
SELinux is preventing cat from 'getattr' accesses on the file /proc/mdstat.

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

If you believe that cat should be allowed getattr access on the mdstat file 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 cat /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
