> http://olstrans.sourceforge.net/release/OLS2000-ext3/OLS2000-ext3.html well, I would not know how the exchange database works, it's an internal format of MS, and so comparing it to another format I'm not familiar with is hardly helpfull :) however ext3 still has a few illnesses I don't like, such as directories are linearly written, and no smart inode and allocation management like in Reiser. v4 is around the corner, and a big list of changes is described, and it sounds a hell of a lot more impressive than any FS I know of to date. it finally sets the foundation for plug-in namespaces, sets up an environment for plug-in handlers, streams, transactions and a lot more. it's way beyond the call of POSIX ofcourse, but I can see real benefits in it for everyone once it comes out (and even much improved speed is one of them! defrag on the fly and "dancing trees".) http://www.namesys.com/v4/v4.html apperently, since it's not very v3 compatible, it may be added to the 2.4 kernel series and not just to 2.5 as a separate new FS type. I can't wait :) -- A totally organic experiance Ira Abramov http://ira.abramov.org/email/ This post is encrypted twice with ROT-13. Documenting or attempting to crack this encryption is illegal.
