:SELinux is preventing /usr/sbin/groupadd from 'unlink' accesses on the file group.
:*****  Plugin catchall_labels (83.8 confidence) suggests  ********************
:If you want to allow groupadd to have unlink access on the group file
:Then you need to change the label on group
:# semanage fcontext -a -t FILE_TYPE 'group'
:where FILE_TYPE is one of the following: pcscd_var_run_t, shadow_t, passwd_file_t. 
:Then execute: 
:restorecon -v 'group'
:*****  Plugin catchall (17.1 confidence) suggests  ***************************
:If you believe that groupadd should be allowed unlink access on the group file 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 groupadd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Tom 2012-04-02 11:06:21 EDT
Happened during yum install
Comment 2 Daniel Walsh 2012-04-02 15:12:47 EDT
restorecon -R -v /etc

And reopen if this happens again.  I guess this could be caused by a problem in first boot.
