> 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.
