Yeah. Basically, there is a kernel service that you can run
user-level daemons against to get fine-grained information just like
with inotify... *but* also the OS runs its own daemon that it does a
good job of keeping alive which writes summaries of the information
(basically, "which directories changed") to a log file and provides an
API to let applications get the summary information without having
their own daemon.
