Re: [PLUG] Moving user accounts - update


i do not see how to login as root under Unity. It just gives a list of available accounts and root is not among them. I have not as yet figured out how to get to a login prompt.

There should be no need for recovery mode. As long as you have the root password you can always just use su to become root (this was the only way to do operations as root in the old days before sudo).
