That thread was what motivated me to write the program, but I must've
missed your post.

Yes, being a shell script isn't a problem. I wasn't aware of
inotify-tools, so I wrote my own. Still, the inotify-tools programs miss
a check for ignoring directories with predetermined contents (I want to
ignore sub-directories with their own git repository).

I think I'll contribute to inotify-tools a switch for that, and switch
to perl. That will simplify the development and allow for coalescing
events, so that updates with temporary files would be a simple update.

FWIW, I also think that trying to keep a coherent stat with automatic
commits isn't possible. As for the temporary, unneeded files, a
exclusion pattern will suffice, and using .git directly, instead of a
(FUSE) filesystem, will allow permanent storage of those temporary
files, until explicitly removed.

Thanks,
