Hmm. What would be the requirements for something like this?
The whole idea of storing to something as complex as a block device when the kernel has been shot to shit seems... a bit undefined?

Yeah, same question.

Think of using read-only filesystems like squashfs (or in extension a corrupted filesystem mounted read-only). Having a binary dump on a blockdevice might help. You might even use an USB stick for that.

Granted, it's not as robust as having some nvram, but better than nothing
