Then it doesn't use getopt(3), or Debian getopt is broken.

It will in 0.1h.

You can argue that this is a bug, but I don't really think it's the
job of login to see if you have any new mail. This feature will become
more and more useless as more and more people move away from
NFS-mounted spool directories. We might add support for this, but then
it will probably be in the form of an external program run by login
(but this is also pretty silly, as you can just as easy add this to
your /etc/profile, or whatever).

This is (one of the reasons) why we don't do this.

You mean authenticating via OTP:s? No, I think there are patches for
MIT Kerberos, but I have't seen them, and doesn't know how or if they
