dmraid handles fakeraid setups such as this. Prior to FC5, dmraid was
not initialized in the boot process, so for example, I installed FC4 on
a fakeraid array the following way:
1. Install to an alternate non-fakeraid drive.
2. Boot Fedora or rescue mode and start dmraid, then create partitions
3. Move partition contents.
4. Patch mkinitrd and create a new initrd with it.
5. Edit grub.conf and fstab appropriately.
I wrote an FC4-specific version of the guide I used, RHEL4 should be
FC5 has an installer that initialized dmraid and contains dmraid in
initrd, so those two main issues are gone, however the 2.6.16 kernel and
dmraid don't get along well yet :/.
