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 
problem.  Get

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[1231]: fixing short FINFO at 4ad8 (seg 74)

After this the regular cleaner should be happier.

Take care,
