I do this!

is this really bad? i would surely like a list of reasons why..

I do it because.. well.. first off, it allows me to have /boot on
different raidlevel than / or /home without extra disks.
secondly, it allows me to with the same disks use different
filesystems.. for instance, it allows me to have /home encrypted with
dm-crypt, while still raided.. Not that i would mind encrypting /
and /home as 1 partition, but it creates a whole slew of issues with
having to create initrd and stuff..

I realize that performance probably suffers abit from this, but well..
is there any stability or security wise risk? i mostly use raid1 and
raid5 only..
