[split] Change password from external media

[James Good]

Hey there, I split this topic from the one you posted it in, b/c they were not related at all.

What you can do is boot a live install from an SD, and use chroot to change the user password. You can use this page as a rough guide (the partitions won't be exactly the same): http://www.microhowto.info/howto/reset_a...ution.html

New (?) question: how or where would I be able to find the file mentioned?  The PBP has Manjaro as the preinstalled operating system and my main computer, a desktop, has Ubuntu 18.04.4 LTS.  What size of SD card might be required?
Thank you,
James Good
