great! i've done that twice to recover something that wasn't
quite right. in both cases help from hardware, and operational
mistakes both were required to get to that point. (using aoe,
lose ethernet connection to mirror of worm while initiating
dump and rebooting instead of fixing the network connection.)
even so, i keep meaning to find the time to fix this bug. the
fs should not care when it goes down.
i've also found that the fworm device was more trouble than
it was worth to me. :-) especially in those cases, you just
rewrite the new superblock on next dump and nobody is
wiser.
