Recovering lost root password

[Erik Hemdal]

Confirmed on FC3.

Interrupt Grub and edit the boot options.  Add the option

single

to the kernel line in your appropriate Grub entry.  This will be the 
"kernel...vmlinuz...." line.

Let the system boot and you will come up with a shell prompt as user 
root.  You can change the password for root there.

When you exit from this shell, you will reboot in the default runlevel.

Sorry for the new thread...I changed machines to test.    Erik
