- Apply SME patches to 11.1.2.259-1 [SME: 7976]
- Update warning about re-formatting attached hard drives [SME: 4788]
- Increase fuzz to allow package to build [SME: 7853]
- No warnings if kernel not upgraded

- No warnings if unable to remove rpm databases
- Always pick best arch for package
- Allow creating/mounting degraded raid arrays
  (log info about degraded arrays instead of not starting them)
- Start /boot raid device first so it will be in sync for grub install
- Automatically upgrade bootloader if necessary
- Log install errors but don't bug user about them
- Search for language updates on upgrade disk
- Force time to be based on UTC
- Add final warning before installing
- Make install headless but still write keyboard info out
  (don't ask us to use vnc mode)
- Make install window wider
  (fix titlebar spacing)
- Don't email root on raid events
- Make boot loader use SME labels
- Determine upgradability of SME server
  (change erase disks to upgrade dialog)
- Run SME post-install scripts on kickstart install/upgrade
- Limit languages to those supported by SME
