Description of problem:
A new directive (similar to pre) which is run after disk partitioning and mounting may allow systems to make early-install changes to the disk before packages are installed.
This would be useful in situations such as https://bugzilla.redhat.com/show_bug.cgi?id=1113885 .
Version-Release number of selected component (if applicable):
Duping this to 1120554. Adding a new special %pre section in kickstart is not the right idea. This needs discussion and design and it may end up being in anaconda or not. Continue the discussion in 1120554.
