SW_RAID in 3.x

[Per Foreby]

I have a few computers using raid1, and in 2.10 I used the tricks at
http://faiwiki.informatik.uni-koeln.de/index.php/User:Svamberg/Software_RAID.
In addition to this, I had to run mkinitrd and create mdadm.conf in a 
script.

Since sarge there has been some changes in software raid, making 
mdadm.conf mandatory, which makes me wonder about the status of the wiki 
page:

1. Just copy the configuration from 2.10 (minus the mkinitrd script),
2. download new versions from the wiki, or
3. avoid software raid?
