Description of problem:
While installing/updating SELinux related RPMs on a system where SELinux is
disabled many of them produce output. E.g.,

  Updating  : selinux-policy-targeted      ####################### [24/64] 
libsepol.mls_from_string: invalid MLS context s0:s0
libsepol.mls_from_string: could not construct mls context structure
libsepol.context_from_record: could not create context structure
libsepol.context_from_string: could not create context structure
libsepol.sepol_context_to_sid: could not convert
system_u:object_r:fixed_disk_device_t:s0:s0 to sid
invalid context system_u:object_r:fixed_disk_device_t:s0:s0
libsemanage.semanage_install_active: setfiles returned error code 1.
semodule:  Failed!


Version-Release number of selected component (if applicable):
3.0.8-42.fc8

How reproducible:
Always

Steps to Reproduce:
1. Boot with SELinux disabled
2. Install/update SELinux related RPMs
3. Notice output
  
Actual results:
Output printed.

Expected results:
No output.

Additional info:
I believe any output from RPM installation/update is prohibited by RPM packaging
guidelines so I am reporting this issue.
