startup sequence without login


Hello

I have an embedded box on which I am developping a driver using a linux kernel. I frequently need to reboot it and relogin as root.

I wounder whether I can modify the boot sequence so that it directly boots into a bash belonging to user 'root'.

I know that this represents a security issue -- looking at my "use case" this is of concern.

Thanks

Tilman

Instead of running getty (or whatever other login manager you are using) on tty1 simply run bash.

If you give more details about the distro you are using we'd be able to give you more specific details about how to go about accomplishing that.

I am using gentoo.

So how do I run bash from inittab and connect it to the tty ?

c1:12345:respawn:/bin/bash ?

Thanks

Not tested (OK, tested loooooooooooooong ago)
Code:
c1:12345:respawn:/bin/bash < /dev/tty1 > /dev/tty1 2>&1

Yep, that should do it. Just tried it on Arch to be sure.
