Add root password reset steps for Silverblue

[barnscott]

I've seen a few people ask for help with root password reset on Silverblue on the discourse forum. This solution worked for me, so I thought I'd share it.

Can someone else test these steps? Would be good to get confirmation that these steps are appropriate and "best practice".

I should note that most of this is heavily plagiarized from another Fedora doc. I assume that is satisfactory, but let me know if otherwise.

Thanks for the steps! Just tested them on my machine (with encrypted drive) and they do indeed work for me aswell. On a side note, I think two of the steps could use some clarification:

• Step 4, considering encrypted drive: I think it should be explicitely stated that the plymouth.enable=0 should be on the next (or another) line, because at the beggining of the step, it is asked to go to the end of the line begining with linux or similar, which might be confusing
• Step 8: The command needs to be run as a root (or at least with sudo, I haven't tested that), and I think that should also be explicitely stated

Also, I am not sure if everyone is familiar with using vi/vim, especially as nano replaced it as a default text editor. I don't know which approach is the best, but in my humble opinion there should perhaps be a link to a tutorial of using vi, or at least a comment that any other text editor such as nano can also be used. This is probably nitpicking but I thought I would share my thoughts about it.

If this is mostly a copy of another doc, could we add a link to that doc instead of copy/pasting the content? If there are changes needed there to adapt to Silverblue, I think it would be fine to add them there.
