Is there any way to be sure of receiving a change notification only after the writer has closed the file? I suppose that such a notification would not obviate flock(2)ing between editors (a quick glance at contrib/nvi shows that vi uses flock) and daemons (although, e.g. inetd simply opens the file without locking) -JG > It would be fairly trivial to monitor a configuration file with kevent, > which would generate a notice whenever the file is changed/copied/renamed, > etc. I believe that John-Mark Gurney had patches somewhere to implement > exactly this for inetd. > > The problem is that under our current model, the administrators do not > expect writes to the file to take immediate effect, and this immediately > breaks POLA.
