If I can boot enough to do dd. I'd need a 2 terabyte thumb drive. Sounds like I need heavier metal, but I should be able to find another heavy-duty backup drive. I guess the thing to do is to make a rescue disk (possibly a live Devuan USB) or the installer an to use that. Or maybe install a small Linux system for recovering the one that works. Having a spare emergency Linux system on disk is probably a good idea anyway. I think I have enough space for that. It will have to understand local text console, IP routing, access to two ethernet intefacing, maasqierading, PPPOE, and software RAID. That's close to a minimal installation, with some configuration copied over from the current working system.
