Securetty: limits root login while allowing 'su -'

["Ennio-Sr" <nasr.laili@tin.it>]

Hi, everybody on the NG.
This is my first post here and I hope it won't be the last one too :-)

[Using Debian/Woody-3.0 on knl 2.2.22 on a home PC.]
I limited root login to two ttys only  (in /etc/securetty) but yesterday
I discovered I could 'su -' to root in the excluded ttys.  Do you think
this is normal behaviour or does my system need re-configuration ?
Thanks for your attention.
Regards,
	Ennio
