True, but it's better than nothing.  I think it also truncates after 7 chars
or so, but that doesn't do you any good.  There doesn't seem to be any other
provisions than gethostname(), but I didn't look that hard.

That is a problem with the Ultrix version of uucp - it's based on Antique
source and doesn't have any of the up-to-date stuff in the current BSD
uucp or HDB.

If you have legitimate access to 4.3 source, run, don't walk and install it.
The only things you lose are per system spool subdirectories and Ultrix
style shared dial-in/dial-out.  The latter is pretty easy to stick in...

No, but a little isty-bitsy bit of object patching lets you create a
version that can be used as a uucp deamon and will do 'g' protocol
over uucp.

This is handled in USERFILE - if you specify a system name/login name
instead of using the default entries, then a mismatch blows of the
suspect system.  Unless the file INSECURE is present, unknown systems
are blown off also.
