   There is a check in FFS for attempts to write out dirty buffers on a
read-only filesystem. I was able to get the machine to panic with the above
on reboot by using tunefs on / (I must have incorrectly used the block special
device). I suppose there is a bug somewhere not returning EROFS when writing
to RO-mounted block devices. I seem to recall that prior to 4.4-lite the system
wouldn't let you do anything with a mounted block device.
