   Ja mam v /etc/inittab jen ctyri konsole, tj. toto je posledni radek

        4:23:respawn:/sbin/getty 38400 tty4

a v ~/.bash_profile

        if [ "`tty`" = "/dev/vc/4" ]
        then
                open -c8 bash
                open -c9 mutt
                open -c10 mc `readlink ~/_` ~/temp
                [ -e _ -a -d _ ] && cd _
                open -c5 bash
                open -c6 bash
                #open -c7 bash startx
                open -c7 bash
        fi

   Prihlasim-li se na 4te konsoli, otevrou se mi dalsi konsole s
pripadnymi aplikacemi.


   Jina moznost je zkompilovat si mingetty s nasl. patchem. Potom lze
mit v /etc/inittab radky typu:

        4:234:respawn:/sbin/mingetty --username hans --nopassword tty4

a byt prihlasen rovnou.


   Dalsi reseni je pocitac nevypinat a neodhlasovat se...
Bohuzel, ale SuspendToHD jsem zatim nerozchodil...



   Zdravi
