our uucp looks at several files for systems data. here is what they are for. they are searched in the order named here. Systems.local entries local to this machine. if you want your own local addenda that won't be shipped over, this is where to put them. Systems.dk systems reachable over datakit. this is constructed from the monthly distribution from indian hill, plus a few local entries (to make sure IH don't break them). it is shipped periodically, so don't bother to make local changes; they'll go away. Systems systems IH don't know about, but we do. alice & research only. Systems1 used for debugging and temporary stuff. don't use it. Systems.gen indian hill phone line data. alice & research only the comets generally have only Systems.dk and perhaps Systems.local (and maybe Systems1, which comes and goes of its own volition). put your local entries in Systems.local.
