This depends on the kind of implementation you have.
In my case I have two different setups which are both able to be powered
down while running.
All you have to do is to make shure that ext2 filesystems are either mounted
ro or resist entirely in a ramdisk.
Writing "configfiles" or data which has to be able to "survive" a power-down
is done via raw-device access or via mtools on a dos/vfat filesystem.
This is just what my scenario looks like, maybee there are other solutions.
