I'm aware of the following references:

Any changes will need to apply to FreeBSD -current, though they may be
back-ported once tested. This means that you will need a -current
system at some point. 8-current is reasonably stable at this point and
would be my suggestion.

The code is in src/sbin/dump. It references various system header
files in order to understand the UFS on-disk format.

No. Dump is completely userland.
