So if I have my Desktop at home, my personal laptop, and my laptop I use for work/business trips, can I have my own personal Linux setup on a portable drive that I can plug into and boot into from any of my devices? Like a cloud Linux setup, but I’m the cloud. Fear my cumulonimbus rumbles!
Yes you can. Here is a little link to help you out.

I didn’t use this method, I have a persistent Linux install on a USB, but at least it’ll point you in the right direction to figure out what you want to do.
