I used inotify-tools both in Gentoo and Ubuntu like this:
inotifywait -rme
modify,attrib,move,close_write,create,delete,delete_self
/home/user/temp
I tried to modify the file and I can see messages like this:
/home/user/temp/ MODIFY host
/home/user/temp/ CLOSE_WRITE,CLOSE host
So I guess inotify works.
In addition, I think everything appears to work correctly except
inotify. In Ubuntu, I started NetworkManager and confirmed that
ifupdown was started and running in managed mode. Modification to
/etc/network/interfaces could be reflected after restart
NetworkManager. But after I modified /etc/hostname, the hostname
didn't change when using "hostname" command. The same thing happened
in Gentoo. No log generated when I modify /etc/conf.d/hostname(Gentoo)
and /etc/hostname(Ubuntu).

Below is the log generated when the nm starts in . I didn't see
anything wrong except one dbus warn.

If there is something I didn't mention, please let me know.
