Hey, fellow Tucsonan! 8-).
I believe BSDI 2.0 did what AIX and UnixWare 2.0 did that caused
identd to break as well: moved the system open file table to be
dynamically allocated.
To get around it, you would have to rewrite the system open file
table traversal code to consider only valid open files from the
read from /dev/kmem.
On AIX and UnixWare 2.0, I hacked this for identd by examining
all active process structures for all processes. It's a lot more
expensive, but since it's not a frequent or time critical operation,
it's OK.
Without BSDI 2.0 source, it's going to be harder, but not impossible.
One potentially easy way to deal with this would be to go to using
/proc instead (this should be more portable as well).
