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!
Absolutely doable. I have had an Ubuntu on a 16Gb stick for years that used any time I had to log into my gmail from a borrowed/friend/relative computer.
