have raid 0 and raid1 on the same drive isn't going to gie you anything
since the raid 1 will "slow" the other raids down.

How do you create several RAID devices if you only have 2 drives?
Is there a way to create virtual RAID sets? That sounds too scary.
You create raid devices over partitions that don't span the entire drive.
Why would this be a configuration that someone would want to do?
So you can have both a 0 (performance) and 1 (redundancy) on the
same physical drives, depending on your partition? Just seems odd.
Thanks,
Scott
What if you wanted /boot and / to be on a raid1 for redundancy, but you wanted
a scratch directory on raid 0 for the speed, maybe for video editing or other
I/O intensive operation?
If you didn't care that the scratch directory failed on a drive fail, you
could get back and running with a reboot and re-creating the filesystem on the
scratch directory.
