Description of problem:

The anaconda that ships with Fedora 17 does not work with an updates image.  The same updates image that works with F15 and F16 does not work with F17.

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

Unknown, the Anaconda that ships with Fedora 17.  The bug is also evident from looking at the latest Anaconda git sources.

How reproducible:

Always

Steps to Reproduce:
1. Create an updates disk with updates_disk_hook.py or a custom installclass
2.
3.
  
Actual results:

Updates disk contents are ignored

Expected results:


Additional info:

There are several bugs at work here I think.  I was able to find workarounds for them, but here is what I found:

- Previous Fedora versions extract the updates disk to /tmp/updates

- Current F17 Anaconda uses dracut (I think) to extract the updates disk to /

- The Anaconda executable (Pthon script) is invoked with CWD set to /root

- The updates_disk_hook.py script is imported from anaconda using the current Python path, which includes /tmp/updates, but not / or /root

- Custom installclasses are searched in pyanaconda/installclass.py (availableClasses()) via "installclasses" (relative path to CWD or anaconda script location, not entirely sure) and /tmp/updates/pyanaconda/installclasses


Anyway, to make F17 recognize my updates disk, it's necessary to manually move the components of the updates disk down to /tmp/updates.

The fix I think is to either change where dracut extracts the updates disk, or to fix up the (many) references in the anaconda/pyanaconda sources to /tmp/updates.
