If you put your swap partitions on both drives without RAIDing them you will/might get

If your not going to RAID swap then just put the swap on one drive so you get a 5

If you don't unders

would
be effectively the same then after the kernel loads from whatever partition
it would
start the raid and then re-sync with the other half of the mirror. RAID 5
would be
an order of magnitue harder as there's striping involved.
Just curious on what the take of this is.

Am I following this correctly: in this senario, are /boot and

Is it safe to assume 2.0.36 is more stable with 0.9x than
with 0.42?

. Commanding the ATA controller requires
initializing a scatter-gather table pointer (outl) followed by 6 outb's to
specify the start sector, transfer length and the direction of transfer.
Is that expensive?
