Sadly, Parted Magic doesn't seem to be all there (???). I get
some errors while it's unraveling squished data to RAM that
some directory it needs is not there. I tried a couple of

There's a systemrescuecd-x86-1.5.0.iso that just finished
burning that's supposed to helpful in these matters as well.
