I have an improved copy of a program handling this for SunOS
which was recently posted in alt.sources by

  | Mike J. Fuller | Internet: mikef@sarah.lerc.nasa.gov      |     "I hate     |
  |----------------|           mikef@zippysun.math.uakron.edu |   quotations."  |
  |/\/\/\/\/\/\/\/\| Bitnet:   r2mjf@akronvm                  | -- R.W. Emerson |

It takes a list of the form:
	{g|u} olduid newuid
on standard input and remaps all of the given UIDs/GIDs on a raw filesystem.
For example, to change UID 42 to 69, 69 to 42, and GID 52 to 105 on a UFS floppy
disk, you would do something like:

% uidchange /dev/rfd0c /var/tmp/checkpoint
u 42 69
u 69 42
g 52 105
^D

It scans through the inode-table of a raw (unmounted) partition and changes
user and/or group ids as configured in the standard input. Cycles are handled.
And it is *very* fast!
Email me and i'll send you a copy.

Disclaimer: I've not written the program, all i did was adding the simultanous 
handling UIDs _and_ GIDs.
