Thread says 2.6.31+ and either a new enough util-linux-ng or parted
are sufficient. Fedora 12 is fine on the kernel side, not certain on
the userspace side. It *can* be done w/older parted, but requires a
bit of manual work partitioning the drive to make sure you get proper
alignment. Anaconda may do that for you already anyway, but I'm not
sure. Newer parted has a -a/--align flag that definitely gets it
right, and is definitely available in Fedora 13. Even an updated build
being available for F12 wouldn't help though if it is indeed required
for Anaconda to get things right, since its the parted built into the
installer image that Anaconda uses. So all that to say... It might
work, it might not. :)

A thought though... Start up an F13 installer. Partition the disk as
you want to use it w/MythDora. Restart the machine and boot the
MythDora 12 installer. Instead of repartitioning, use the existing
partitions, which should all be properly aligned. Proceed w/the rest
of the install as normal.
