[ale] Changing OS's on a pc with RAID

[Drag0n]

As long as the new OS uses the same general kernel version, the raid
array will auto detect and mount as what was specified before. I have
had issues where i was trying to make some changes to drive structure
and because of the superblock on each partition being tagged with what
it was, it kept trying to reorder all my drives.
 You should be safe, but it never hurts to back up everything before
just in case.
