So /etc/ttys becomes Yet Another Database. Makes some amount of
sense. You have a tty name, and a bunch of attributes, and init,
getty, login (anything else? su?) queries it. All we need is a solid
list of the current queries... does it need any more sophistication
than that? (The regexp/glob issue then becomes an issue of how the
*user* manipulates the database, the applications don't care.)

Dynamic update would be good too -- let rlogind indicate that the pty
it just opened is on a kerberos-authenticated, encrypted connection,
or an ssh encrypted connection, or whatever -- so the things that ask
"is this tty secure" can get a yes (at site admin's whim of course)
and likewise get a "no" if it's a classic password telnet. Could be an
interesting extension -- and isn't a good part of the value of a new
subsystem how you can use it in interesting ways? (otherwise it's just
a gratuitous change and everyone will hate you for it :-)
