The rules are as follows:

	Vanilla v7 UNIX:	Change the name in uucp.h, whoami.h, and mail.c
				and recompile UUCP and /bin/mail.

	2.8 BSD:		Same as above

	4.1 BSD:		Same as above

	4.2 BSD:		Execute the hostname command.

	2.9 BSD:		Same as above(???)

	UniPlus v7:		Edit /usr/lib/uucp/SYSTEMNAME
				Make certain that your release has the /bin/mail
				that uses this, instead of the compiled in
				name ``UniSoft''. This bug was fixed 1.5 years
				ago, and if your system mfgr hasn't gotten
				a new release since then, it's their own fault.

	XENIX:			Does anyone know whether they fixed this? Or
				Are they just like Vanilla v7 (without source,
				of course)?
	
	System III:		Execute /etc/chgnod and reboot the system.
				chgnod adb's the kernel, but you need to reboot
				to have it in core. UUCP and mail use the
				uname(2) system call to fetch this. Unfortunate
				that there isn't a system call to set it...
	
	System V:		Same as above

	UniPlus System III/V:	Same as above

The bad guys right now are any 68000 system manufacturers who are still
distributing v7 UniPlus with the old UniSoft /bin/mail with that
compiled in name. I forced UniSoft to fix it quite some time ago (April
of 1983), but not everyone has bothered to get the update...

Does anyone know whether microsoft has fixed this problem in XENIX
(either by going System III completely or by hacking it out into a file
like UniSoft did for v7?)
