This is slightly OT, but I was looking at the AsiaBSDCon site yesterday=20 and I saw this: http://asiabsdcon.org/timetable.html#P11 "This paper introduces Bluffs, a journaling file system that is mostly=20 compatible with the Fast File System (FFS) on disk structure. The FFS has= =20 been successfully used for a long time. However increased disk capacities= =20 have made the classic crash recovery using a file system checker (fsck) a= =20 prohibitively time expensive operation. Soft Updates [4] and background=20 fsck were introduced to combat the problem but added code complexity to=20 FFS. Bluffs goal is to replace FFS by providing the same functionality as= =20 FFS with better error recovery and a fresh simple code structure. Allowing= =20 bidirectional migration of file systems between FFS and Bluffs format=20 should make transitioning easier, provides file system checker tools to=20 Bluffs and allows booting with the standard bootstrap loaders." This is the first I've heard of this. It seems to be coming from Yahoo!. Anyone else know anything about this project? Thanks, Charles > -- > Vaclav Haisman --0-2057729563-1171309474=:28160--
