Other Directory/File sync based on fsnotifier

Hey all,

Linux have inotify to monitor individual files, or to monitor directories. When a directory is monitored, inotify will return events for the directory itself, and for files inside the directory.

Poor BSD has lacked this for some time, but it seems one clever guy has filled in the gap


Has anyone looked at this as a way to instantiate something like Rsync or something similar? Even possible zfs send/receive?
