Okay, here goes.  I have a unfragmenter which is modified from the
fsanalyze programs.  It is, I think, bullet proof, but also slooow.  I
use it on my own system (uPort SYSV/386 3.0e) and have no problems
(now ;-).  I borrowed heavily from the fsanalyze sources, and really
only wrote a small portion of code myself.  The method I used will
unfragment a file, but does NOT compact the disk (intentionally).  I
have it set up to allow the user to selectively unfragment files from a
list which is generated by the fsanalyze code.  It then attempts to make
multiple copies of the file and selects the least fragmented.  I am sure
there is a better way (look through the free block list maybe?).
Anyways, if anyone is interested in a copy of it, send me a message
requesting it, or if someone tells me how, I can submit it to a group.

NOTE:  This program may be very SYSVish in my mods, I've never used BSD.
