Bug#928662: Summary

[hoxp18]

Dear maintainers,

After I tested some more conditions,
I guess the situation is something like this.

Case 1. Text compositions in GUI apps cause time-delta log flood
-----------------------------------------------------------------

It seems using IBus-Mozc does not have direct relationship.

Typing without Mozc did also triggered log flood.

Case 2. CLI apps in GNOME terminal like vim.nox cause no log flood
-----------------------------------------------------------------

Note that vim.nox has my own AppArmor profile, enforce mode.
(as I reported, Firefox/Thunderbird, Mozc also have enforce profiles)

I use it both direct English input and Japanese input using IBus-Mozc.

Conclusion
==========

Since Buster release note says AppArmor be enabled,
I think this report should be shared among those teams;

   AppArmor, GNOME, IBus, Mozc, Firefox and Thunderbird.
   (and some other teams working on them.)

/var/log grows almost twice as faster as Stretch.
(perhaps because of this log flooding.)

Here is a comparison.

Stretch:

Buster :
