The trick in the NetWare 3 model was to segregate the directory
entries onto special reserved
4K directory blocks (128 byte dir records). When it came time to purge
storage after the file system filled, an entire 4K block and all
chains was deleted during block allocation for new files. The dir
blocks were ordered by date -- oldest ones got purged
first. The model worked very well until compression was added to the
filesystem, then it started getting complex.
I would be willing to help instrument the NetWare 3 model in this
proposal on ext3, since this is a basic versioning model and
would provide coverage for 99% of the folks needing this capability. I
am available for questions.

I resigned as Chief Scientist of Solera Networks May 8 this year --
mostly because I was not allowed to have any freedom, including working on
free Linux projects. This went on for almost 4 years (since 2003). Now
that I am independent again, I can work on stuff like this again. I
started a new company with John Noorda (Ray Noorda's oldest son) who
runs Canopy now. That's my current status. I am an owner and entrepeneur
again. So I have a lot of free time and will from now on.
