Description of problem:

When running cobbler sync with the latest cobbler 2.2, it fails with AVC denials.
The cause is very similar as the bug 813206, this time for directory /var/www/cobbler/images.

Version-Release number of selected component (if applicable):

# rpm -q cobbler
cobbler-2.2.1-1.el6.noarch

How reproducible:

Deterministic.

Steps to Reproduce:
1. Have Spacewalk nightly installed, have some kickstarts defined.
2. Workaround bug 813206, bug 816596, and bug 816834.
3. Run cobbler sync.
  
Actual results:

Additional info:

When run in permissive, the AVC denials are

So the problem is indeed with the /var/www/cobbler/images directory missing from the cobbler-2.2 rpm, which is a regression against cobbler 2.0.

With bug 813206, bug 816596, bug 816834, and now this one, isn't it time to revert to cobbler 2.0 in EPEL ASAP?
