No, fsck doesn't pay attention to the segment headers (except during roll
forward, and then only very new ones). This is really only a problem for
the cleaner and for roll-forward. An up-to-date kernel takes care of roll
forward, so if the cleaner can work around it there will be no problem.
I've hacked the not-quite-ready new cleaner into a tool to fix this
and unpack it in /usr/src/libexec , parallel to the existing cleaner
source dir. Build it (but don't install it!) Unmount your filesystem.
Invoke the cleaner with -d and specifying the raw disk device as the
filesystem to clean:
./lfs_cleanerd -d /dev/rwd0g
It will give you lots of messages like
lfs_cleanerd: fixing short FINFO at 4ad8 (seg 74)
After this the regular cleaner should be happier.
