I suspect this will mean that journalled ext3 when the system crashed 
(so the filesystem "needs recovery" from the journal) won't load.  (Of 
course, properly speaking that would load grub's code to replay the 
journal...)  But I think that (without other changes) that would make 
the system unbootable every time there was a power outage?  (Of course 
it was not guaranteed to load correctly when ignoring the journal when 
it needed recovery, but it was likely to work, IIUC.)
