It seems to me that the ideal device to hold an external journal is a
battery backed RAM based MTD device. Does such a beast exist?
As an alternative, has anyone considered or implemented a more
conventional ramdisk that would be preserved across a kexec crash, in
conjunction with an oversized UPS and NUT configured to suspend the
system with plenty of battery power left?
