The default ttys entries are
# name getty type status comments
console "/usr/libexec/getty std.38400" vt100 off secure
ttyE0 "/usr/libexec/getty std.9600" vt100 on secure
tty00 "/usr/libexec/getty std.38400" vt100 on secure
That won't let me log in.
NetBSD/macppc (StarFire) (tty00)
root login refused on this terminal.
Jan 21 22:42:46 StarFire login: LOGIN root REFUSED ON TTY ttyZ0
If I change the last line to ttyZ0 it works. Weird. Looks like getty is
parsing the name of the symlink in one place and the target of the link
NetBSD/macppc (StarFire) (ttyZ0)

The nice thing about Windows is - It does not just crash, it displays a
dialog box and lets you press 'OK' first.
