kernel RPM install avc message

[Dax Kelson]

I have a fresh FC2T2 install. I did the following to make up2date work:

/usr/bin/setfilecon system_u:object_r:rpm_exec_t /usr/sbin/up2date

Then I ran "up2date-nox kernel"

The following appeared. It seems the kernel did install OK.

audit(1080787992.351:0): avc:  denied  { search } for  pid=20375 
exe=/bin/bash name=root dev=hda8 ino=179873 
scontext=root:sysadm_r:bootloader_t 
tcontext=root:object_r:staff_home_dir_t tclass=dir
/bin/bash: /root/.bashrc: Permission denied
audit(1080787998.806:0): avc:  denied  { search } for  pid=20791 
exe=/sbin/grubby name=root dev=hda8 ino=179873 
scontext=root:sysadm_r:bootloader_t 
tcontext=root:object_r:staff_home_dir_t tclass=dir

What was the working directory at the time you ran up2date?  Was 
it /home/something?

We don't want to grant such domains wide access, and we also don't want large 
dontaudit rules (they increase the size of the policy, increase kernel memory 
use, etc).

Is it acceptable that sometimes if you run something from an unusual directory 
then it will cause an audit message?

Messages will be gone in tomorrows build.
