But you can, even for physically distinct machines: just package-up your emacs/environment/shell/etc profile into a bash-bunny USB stick, such that the bunny uses its keyboard emulation to type-out and run the commands that load your profile into your current machine.

Not everyone works on the machine they are sitting in front of.

That's why storing your conf in a keyboard input device is so nice, works as long as you can insert your own keyboard. I think I might start doing that, but the systems I remote in to are so different can not be sure emacs/vim is there.

I would recommend a Raspberry Pico as a fake keyboard, it has 2MB of storage. But that all falls apart when you are not allowed your own USB devices...

Right, that's why I said to use a Bash Bunny: it's a USB mass storage stick that can also emulate a USB keyboard (there's a few buttons on the stick to switch modes), so you'd be at the computer, open up a terminal and open the editor for a new bash/emacs config file, then plug-in the stick in keyboard mode and press the start button on the stick and after a few seconds it should have dumped kilobytes of data into the file which you can then save locally and so take your bash/shell/emacs/etc settings with you, even without needing USB mass-storage support (given many companies disable USB mass storage to mitigate data-exfiltration but, of course, need to allow USB mice and keyboards).

Unlike most things in the comments above, I have no clue what you are talking about and highly doubt many people do.

bring your $HOME/.emacs.d around with you, pretty easy :)
