Booting Into Single User Mode with GRUB

Hi all.  You can use the append mode in grub that Doug was describing,
and append init=/bin/bash to get just a shell prompt.  You then have to
remount the root system as rw, for example mount /dev/hda1 -o remount,rw

Now you can use passwd to change the root password.  The problem with
this approach is that when you reboot, your system will perform an fsck
because the reboot doesn't gracefully unmount file systems.
