Hardware raid can boot from anything of course.

Software raid, not so.

I personally use a 50GB raid 1 for / and another 50GB raid 1 for /home,
and then the remaining space on my 4 drives as a raid 5 for LVM to store
everything else (like most of /var and other data heavy locations on a
mythtv box).

Even mdadm with bios fake raid is tricky, although less so than device
mapper was.  Pure linux md software raid is by far the simplest and
most reliable.
