I'm guessing Daniel is referring to NetApp/WAFL issues. NetApp's WAFL
filesystem (IIRC) implements something which is kinda sorta if-you-squint-
your-eyes philosophically similar to tux2's phase tree. Only
a) It isn't *really* all that similar
b) Daniel has prior art going back to the 1980's
c) NetApp has more lawyers on staff than Daniel does
Daniel, did I get it vaguely right?

Well perhaps the patent part, but I sort of got curious
on it, by this posting. Is there any patches or documentation
available. I'm going to put my nose deep into the world of
experimental file systems this winter, and hopefully come up with
something useful, so I would appreciate anything that describes
it's general ideas.
kind regards

See:
Borg, Wolfgang Blau, Wolfgang Graetsch, Ferdinand Herrmann, Wolfgang Oberle: Fault Tolerance Under UNIX. TOCS 7(1): 1-24 (1989)
1986
also:
Anita Borg, Wolfgang Blau, Wolfgang Oberle, Wolfgang Graetsch: Fault Tolerance in Distributed UNIX. Fault-Tolerant Distributed Computing 1986: 224-243
1983
Anita Borg, Jim Baumbach, Sam Glazer: A Message System Supporting Fault Tolerance. SOSP 1983: 90-99
The earliest description I've heard of this idea was from Sam Glazer in 1982.
