Description Rob K 2011-09-07 04:35:57 UTC
SELinux is preventing NetworkManager from 'unlink' accesses on the file /etc/resolv.conf.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If you want to fix the label. 
/etc/resolv.conf default label should be net_conf_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /etc/resolv.conf

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you believe that NetworkManager should be allowed unlink access on the resolv.conf 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 NetworkManager /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Did you move resolv.conf from your home directroy?
