[Bug 882147] Re: overlayfs does not implement inotify interfaces correctly


@Alf Gaida Most ppl can't read, it's unfortunate.  To communicate with
ppl one must repeat themselves like an advertiser a 100 times, no a 1000
times is not even enough.  Computers read vary well and what's more is
if you adjust your phrasing slightly enough times eventually you'll get
total obedience.  Thus communicate with humans repetitively even past
the point where the audience thinks that your actions are argumentative
is the only way I've ever known how to get even the most basic
understanding across.

I'll keep pointing out that ---disable-inotify is a good solution and
merits being made into a feature.  Plus there are a multitude of ways to
fix this and there is a deficit in only perusing one single-mindedly.

The compliance of a single person is irrelevant.

Bug description:
  When using tail on the liveCD some updates are not reported.  This
  seems to be triggered by tail using inotify to identify modified
  files.  Overlayfs does not appear to be implementing inotify quite the
  way you might hope reporting only against the underlying filesystems.
