I stumbled across this sort of fascinating area of doomsday prepping a few weeks back.
A nice addition to that, don’t just make it a USB, but a raspberry pi. So you’d have a reasonably low-powered computer you could easily take with you.
Not suggesting this one as it seems a bit expensive to me, but https://www.prepperdisk.com/products/prepper-disk-premium-over-512gb-of-survival-content?view=sl-8978CA41


I haven’t switched to it full time, still happy with KDE… but niri is really nice too
