Nope, I'll definitely take look.  Already imported it into git using =

git-cvsimport.  :)

I'm always interested in [legally] stealing useful ideas and code, so I =

will definitely take a look.

I was sorta thinking about implementing a couple backends, and seeing =

what API organically appears.  That's sorta how Linux kernel API =

"design" happens, and it tends to produce something useful and compact, =

if not a bit unique :)

I can imagine that some backends may wish that the server handle some =

details of state and locking, while other backends may wish to record =

all that information into a database in stable storage.  So it's =

difficult to forecast how all that will fall out in the end.  unfs3 =

probably has many lessons to teach me...

So far my best resource for NFS technical "folklore" is generally =

google, which turns up a wealth of useful mailing list discussions =

involving neilb, meisler, and others.

P.S.  cvsps, the util git-cvsimport uses, doesn't seem to like the unfs3 =

CVS repository.  Any ideas?

Running cvsps...

The same command works just fine with 99% of cvs repositories out there, =

pserver, ssh, or whatever.

And a regular CVS checkout works just fine, I am able to check out and =

browse files and look for gems.
