    At first thought, I thought that we should integrate our numbering ASAP.
But, upon further reflection, it occurs to me that there may be routines in
the kernel that check the version upon compilation or execution.

    Also, are we really wed to using Linux as a base? I thought that I had
mentioned a couple of weeks back that there is another home-grown kernel
group working on an "open source" OS compatible with Win NT. It occurs
to me that since it is pretty widely held that NT was in many ways a VMS
clone since Dave Cutler was the architect of both systems. Since this group
is still pretty early on in it's development, there would not be a decade's
worth
of cruft to wade through to implement a VMS clone.

    I also ran across two interesting articles in the December 2001 issue of
Dr. Dobb's Journal: two new "open source" systems, Menuet OS and NewOS.
Of the two, it appears that NewOS would be the better of the two to
implement
a VMS clone upon.

    Does anyone have any idea what happened to the code and libraries that
had already been accomplished by Rich Levitte's group? As I recall, they
had several system libraries partially cloned, as well as a DCL compatible
command processor.

    I'm not pooh-poohing the use of Linux as a base; I just wanted to make
sure that we had evaluated our options before spending a lot of resources
to this current tract.

    Best,
