   What fanotify SAYS it will document is not really
   what it WILL document. The authors complain that
   even new kernels do not support the most useful
   (esp to me) file events. They were "supposed to"
   quite some time back, but still do not. Bullseye
   certainly doesn't.

   I need Create/Modify/Delete at minimum for my project
   with Delete being just as important as the rest.

   I'm still not entirely clear about the 'efficiency'
   of fanotify (or ionotify) when it comes to documenting
   said events across ALL disks/volumes. They are both
   more oriented towards watching a SINGLE file, or at
   most a single subdir, and I'm concerned that trying
   to scale them up means the damned things would literally
   try to separately watch EVERY file in there - of which
   are hundreds of thousands.

   So, I don't want to watch a file for changes, I'm
   looking for a tap just a bit above there where the
   system has decided it's gonna do something with
   one/many files/folders/disks but maybe hasn't even
   passed that along to the lower-level stuff quite yet -
   where you only have to watch ONE var or buffer or
   whatever. That would be efficient.

   So far ... nothing quite like that.
