Tomas, it would have been nice to inform us Unionfs developers before making
that change.  The choice is indeed yours and everyone else's.  You may not
appreciate the amount of effort that goes into getting into -mm and beyond.
But since you do own the unionfs.org domain, I think it's your
responsibility to be fair, not "the bad guy."  Calling our Unionfs "dead" is
irresponsible and plainly unprofessional of you.

Unionfs is far from obsolete or deprecated.  If you will be on this mailing
list a little longer, you will see patches we submit, both to -mm and as
standalone, which will address the following:

- cache coherency and mmap, done the right way (we're presenting it at LSF
  *today*).

- dynamic branch management.  This is done, just needs through testing.

- an on-disk persistent store, and idea suggested by Ted Ts'o at OLS 2006,
  which fixes (this is 80% coded)

  + whiteouts and opaqueness
  + stacking Unionfs on top of Unionfs
  + persistent inodes
  + rename
  + readdir/seekdir
  + hard links
  + resuming previous mounts with a simple handle

Remember everyone, our goal is to get Unionfs into the mainline kernel,
which means we have to do things *right*, efficient, and comply with the
many important things that kernel developers look for.

Stay tuned.

Sincerely,
Erez, on behalf of the Unionfs team.
