[arm-allstar] The forgotten root password blues

[Doug Crompton]

You have to remove the SD card and mount and edit it on another system.
Putting the card in a reader and putting it into a Ubuntu or a Pi Raspbien
system it will mount automatically and you can look at and edit files
(carefully).

The bottom line though is that if you have not made a lot of changes on the
system that you lost the PW on then it would be much easier to just run
firsttime.sh and re-setup. Most of your prior answers will be presented to
you and you can have it back up and running in minutes.
