Hello.
Last N systems I've installed, I am usually assembling software raid1 at install time. The disk layout I'm using is trivial: 100MB + the rest, where on 1st 100MB is /dev/md0 (ext3, /boot) and the rest is /dev/md1 (lvm, other).
For whatever reason (haven't looked at the code yet :() anaconda issuing mdadm commands in such order that primary replica of unsynched md0 is second drive, and raid1 resync started first on md1.
So, to boot without changing bios settings back and forth (or without disabling 1st disk drive by any other means) it is nesessary to wait while md1 raid1 resyncs, which can be as long as 2 hours (250GB HDD).
I'm pretty sure that anaconda at some point deliberately did things to avoid that sync. So I suspect it got reenabled for a good reason...
