If you're referring to the long list of copyrights that come up after
the date prompt, the list is generated by one of the rc scripts, and the
actual text comes out of files in the /etc/copyrights directory.  You
can take it out by editing the rc scripts, or moving the contents of
/etc/copyrights somewhere else, but be warned that you're probably
invalidating your license or something silly like that.  I don't really
consider it a large problem, so I haven't bothered to do anything about
it.

If you're referring to the list that gets displayed after your last
login information, and before the /etc/motd file, then yes, it comes
from /bin/login.  You could probably null out the text if you wanted
to, but it's much easier to either (a) ignore it; or (b) replace
/bin/login with one of your own creation.  The only problem with
(b) is that it doesn't set your LUID, so you'll either have to use
the PD library for that, or write your own.

No, that comes out of /etc/gettydefs, and can be rather easily changed
to your own favorite message.  My only beef is that SCO getty doesn't
seem to support /etc/issue or a similar file, and limits the "identification
field" of /etc/gettydefs to 89 characters.  Yuk.
