No, inotify does not support watching directories recursively. I would love to add it, but it would be a mess to do inside of the kernel.
Making it easy and efficient to watch a full tree, however, was a goal of inotify. Beagle, a personal indexing infrastructure, watches the user's entire home directory.
You could never do this in dnotify because you would run out of file descriptors and pin every file.
In inotify, it is not hard to write a simple recursive loop to add a watch to each directory starting at a given path. It can even be done in an atomic fashion. See
http://mail.gnome.org/archives/dashboard-hackers/2004-October/msg00022.html
wherein I publish such an algorithm.
Hope this helps,
Robert Love
