	This was true before System V Release 2 (SVR2).
With SVR2 on the 3B2 (I'm not sure about SVR2 on other machines),
one can issue the command

		uname -S new-name

to change the ``UUCP node name'' (it changes the "sysname"
and "nodename" parts of the "utsname" structure in uname(2)).

	Also, as far as just ``UUCP node name'' is concerned
(i.e. the name UUCP calls the local machine when communicating
with a remote machine) this can be changed with the (undocumented)
MYNAME= field in the Permissions file (SVR2 again, or with
HDB UUCP).
