Description of problem:
SELinux is preventing /usr/bin/rm from 'unlink' accesses on the file /etc/prelink.cache.

*****  Plugin restorecon (94.8 confidence) suggests  *************************

If you want to fix the label. 
/etc/prelink.cache default label should be prelink_cache_t.
Then you can run restorecon.
# /sbin/restorecon -v /etc/prelink.cache

*****  Plugin catchall_labels (5.21 confidence) suggests  ********************

If you want to allow rm to have unlink access on the prelink.cache file
Then you need to change the label on /etc/prelink.cache
# semanage fcontext -a -t FILE_TYPE '/etc/prelink.cache'
where FILE_TYPE is one of the following: prelink_cache_t, prelink_log_t, prelink_var_lib_t, systemd_passwd_var_run_t. 
Then execute: 
restorecon -v '/etc/prelink.cache'

*****  Plugin catchall (1.44 confidence) suggests  ***************************

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

Comment 1 Daniel Walsh 2013-07-09 17:30:20 EDT
Alert tells you what to do.

If you want to fix the label. 
/etc/prelink.cache default label should be prelink_cache_t.
Then you can run restorecon.
# /sbin/restorecon -v /etc/prelink.cache

Any idea how this file got created with the wrong label?
