gjournal and Softupdates

[bsd at kuehlbox.de]

I've just watched over some of the gjournal threads.

My main question now is, whats the difference from gjournal and 
softupdates in case of reability ?
Wasn't SU design to make the use of journals needless? As far i 
remember, SU was designed to write in the cache in such a way, that 
whenever the system crashed, the FS is always consistent. Only bgfsck 
has todo a snapshot and cleanup "unused" space that got lost cause the 
SU did not finish as the crash occured.

Maybe someone can give me some light into that :). I always tought that 
*BSD don't need a journaling FS as it has already SU
