As of Rev 2.0 I know of these "bugs"

1. ppdd has only been tested on Intel x86.

2. sparse host files are not supported.
   (if you use dd if=/dev/zero of=ppddfile bs=1k count=xxx
   or if you a real device you will not hit this problem)

3. I strongly advise that partitions used for ppdd are a multiple
   of 4096 bytes. An obscure bug in Linux can bite you otherwise.
   It is very unlikely you will encounter this problem but if your
   partitions are multiples of 4096 you will be 100% safe as regards
   this problem.

4. None of the utilities sanity check what you are doing. For example
   nothing stops you doing an encryption in place on a mounted patrition.
   Similarly there is no check that you don't overwrite the entire disc
   when you probably wanted a partition. e.g. using /dev/hda instead of
   /dev/hda1. Please double check what you are doing before using
   potentially dangerous commands.

5. On some machines random numbers are not produced quickly enough. The
   simple fix is to run "find / >/dev/null" in another session. That causes
   enough real disc activity to wake up the random number generator.
