yes.  recover doesn't touch the w part of the device.  it just checks the
block after the last block in each dump to see if it's a sb.  if it is it
loops.  if it is not, then you're at the end and the cache is cleared.

kenfs does run on new hardware.  i'm currently running it on an
intel 5000-series processor and a brand new mb at coraid.  it also
does great with my valinux pIII at home.

electricity:  $5/month.
noise: too much.
not doing maintence to the fs: priceless. ☺
