SELinux is preventing /usr/sbin/prelink "unlink" access to deltarpm.4UeAbd.

Detailed Description:

[prelink has a permissive type (prelink_t). This access was not denied.]

SELinux denied prelink unlink on deltarpm.4UeAbd. The prelink program is only
allowed to manipulate files that are identified as executables or shared
libraries by SELinux. Libraries that get placed in lib directories get labeled
by default as a shared library. Similarly, executables that get placed in a bin
or sbin directory get labeled as executables by SELinux. However, if these files
get installed in other directories they might not get the correct label. If
prelink is trying to manipulate a file that is not a binary or share library
this may indicate an intrusion attack.

Allowing Access:

You can alter the file context by executing "chcon -t bin_t 'deltarpm.4UeAbd'"
or "chcon -t lib_t 'deltarpm.4UeAbd'" if it is a shared library. If you want to
make these changes permanent you must execute the semanage command. "semanage
fcontext -a -t bin_t 'deltarpm.4UeAbd'" or "semanage fcontext -a -t lib_t
'deltarpm.4UeAbd'". If you feel this executable/shared library is in the wrong
location please file a bug against the package that includes the file. If you
feel that SELinux should know about this file and label it correctly please file
a bug against SELinux policy.
