Oops. I misread that the first time I answered.
That is, believe it or not, standard Linux behaviour. Linux's login
is unusual in that it calls the "vhangup()" function to reset the
tty; it's rather like pressing a "Secure Attention Key" (a "SAK")
on a terminal. It's been this way for several years, at least, and
we haven't changed it.
If you want to change this behaviour for yourself, you can do so
by removing the call to vhangup() in the login source, but I can't
*guarantee* that the result will be good.
If you want to use "login" on the command line like that, I recommend
aliasing "login" to "exec su -"
Hope this helps,
