I'd never thought much about this issue before reading this article, but
a thought occured when I did: rather than trying to save a crash dump
to a disk file, why not send it over a network to a crash dump server
on another (i.e., not currently not crashing!) machine?
Thus the local disks need not be touched - one would need to have a
working network stack though (doesn't the console logging over-the-network
stuff have some useful stuff for this purpose?).
The result might be small/safe enough to be in the main kernel, and hence
not require all that crash-kernel memory!
Just a thought!
