WRONG! getty's are spawned by init when (1) the system is started and
(2) When someone logs off (ie: login process terminates) or when the
current getty on the line dies. CD is only up when someone has dialed
in. Getty is also present when no one is connected. It simply waits
for a call to come in, and then prints the first "login:" prompt. When 
someone types in a login  id, it exec's /etc/login (or /bin/login) with
the string typed by the user as its argument. /etc/login validates the
user (makes sure he types in the correct password) then takes care of
some other login accounting, then exec's the user's login shell as listed
in /etc/passwd.
