Also Knoppix.

You'll lose data if you toggle power, no matter what.  You may be able
to avoid an fsck, but that's a matter of filesystem integrity.  Complex
systems such as databases may be fried in a very bad way (though a
proper ACID database should reduce to the prior case of data loss rather
than integrity loss).

What is the system intended to be used for?
