I thought this problem was resolved in later releases of the XFS driver (>2.4.13 kernel versions). I saw a noticable diff in stability with the later kernel releases. Although, I haven't been performing unclean shutdowns here to test the idea, but in earlier kernel versions, this was a real annoyance since I would find allot of my user config files completely wiped :-( I've yet to see this problem persist in later kernel versions, although, every now and then, i might come across an improperly formated config file starting with @@@@, but moving further down in the file reveals the config settings. I don't know if this is really XFS related or vim related for sure. if you atleast do a alt+SysReq+S before a unclean shutdown, you should be safe! this is the route of the problem/bug here. basically, the XFS mailling list has more indepth detail about the sync bit (err...whatever). -- Roger ----- Verify my pgp/gnupg signature on my HomePage: http://www.alltel.net/~rogerx/about/index.html
