Description of problem:
SELinux is preventing /usr/lib/systemd/systemd-hostnamed from using the 'dac_override' capabilities.

*****  Plugin dac_override (91.4 confidence) suggests  ***********************

If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system
Then turn on full auditing to get path information about the offending file and generate the error again.

Turn on full auditing
# auditctl -w /etc/shadow -p w
Try to recreate AVC. Then execute
# ausearch -m avc -ts recent
If you see PATH record check ownership/permissions on file, and fix it, 
otherwise report as a bugzilla.

*****  Plugin catchall (9.59 confidence) suggests  ***************************

If you believe that systemd-hostnamed should have the dac_override capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep systemd-hostnam /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2013-09-03 06:05:21 EDT
Could you turn on full auditing

# auditctl -w /etc/shadow -p w

Try to recreate AVC. Then execute

# ausearch -m avc -ts recent
