Off-Topic Question

> As for background FSCK, DragonFly is currently
in development of adding in journaling support and is just a few 
months away from completion.  The background fsck method has many 
fundamental flaws hence the reason for development of a different 
method.  Our jorunaling work will allow the system an even greater 
degree of flexibility as you will able to do things such as real-time
remote mirrored filesystems.
Can you point me to the necessity of adding journaling to UFS? I thought 
Softdeps haven been a comparable solution to the same problem journaling 
addresses. Both's performance penaltys over async metadata writes seem 
to happen in the same universe.
