How to cancel the login?

Hi,

How can cancel the login and password when uclinux start up!

The first program kernel starts is /sbin/init. If you put your shell there with that name, you'll bypass the rc, inittab stuff.

Or, you can let agetty starts up your shell directly, not the dummy login, by modifying the agetty.

If you add "single" to the kernel command line, init should exec /bin/sh without executing the

startup script (/etc/rc). This will allow you to bypass the getty/login without changing the

filesystem. When init starts in single mode you should see something like this from the console:

Booting to single user mode.

Unfortunately, the current microtronix linux port does not support command lines passed

by a boot loader. Also, u-boot does not pass "bootargs" to the kernel yet either.

So you'll have to rebuild the kernel.

I'll update u-boot and submit a kernel patch to support boot loader command

lines -- once I find some time 8-(
