Single User Mode

From Single User Mode, I like the following extract for root password recovery:

If you get asked for the root password when entering single user mode use 'init=/bin/bash' on the kernel append line which should 
boot the machine into a bash console where you can get read/write access to your /etc/shadow file. You can then either run `passwd` 
or edit the shadow file directly to put in an empty string. This allows you to reboot the machine into its normal environment and 
login as root leaving the password blank and then run the `passwd` program to set the root password. This should really only be done 
when the machine is detached from any networks.
