Actually it was Coda 4 that remained under the BSD license. The
difference between Coda 5 and 6 was the introduction of realms.

So instead of going to /coda/usr/jaharkes, I now have to access
/coda/coda.cs.cmu.edu/usr/jaharkes. The important kernel difference is
that we went from 96-bit file identifiers to 128-bit by adding a 32-bit
realm-id.

Aside from the inconvenience of having longer pathnames the initial
versions with the dynamic root were not neccesarily as stable. I think
it took at least 5 or 6 iterations before we got to a point that was
somewhat comparable in stability.

Same thing with coda-6.9.x clients, which use only write-disconnected
operation and although that code has been around for a long time, we
were never forced to really to rely on it 100%, so all those little
nagging problems that have been around for a long time but were hard to
reproduce or pin down are now pretty much unavoidable.
