Honestly, carrying around a usb drive is generally a pretty good idea. I carry one with several ISOs so I can rescue a machine if something happens and I am unable to fix it (and also show people what modern Linux has to offer).
This is something I carry pretty much anywhere I take my computer, and would recommend to most people. Sure, I could leave it at home, but if I have to meet a deadline, I don’t want to spend the extra hour driving to my house. It’s a worst case scenario kind of thing, but it pays off considering how little effort takes.
Everyone was talking about it back in 2022, but it hasn’t really had any progress since then. I had attempted to use it, but it was rather unpolished.
