The Root Raid HOWTO is seriously out of date and is based on the 0.42
raid tool set. The current .9x tool set is different in it's setup
and configuration. Raid is still alpha but seems to be pretty stable now
with a real nice feature set. I will update the HOWTO, hopefully in the
not to distant future when time permits and raid 1+ is not so alpha.
If you have specific questions about booting initrd ramdisk, etc... I
will try to answer them or point you to the document with the answers.
