>Description:
I discovered recently that although fsck_ffs -n claims it's replaying
the journal, it actually doesn't, because fsck doesn't have the
infrastructure necessary to support replaying the journal without
writing to disk.
I fixed the prints so it no longer claims this; however, since running
fsck without having replayed the journal isn't especially meaningful
or helpful, it would be better to add this functionality.
>How-To-Repeat:
crash, fsck -n, observe inconsistencies, mount and unmount (which
replays the journal), fsck -n again, inconsistencies have disappeared.
>Fix:
SMOP but not entirely trivial :-|
