Control: tag -1 + moreinfo > AppArmor 2.13 fails to start if I set `features-file=` in parser.conf:
[...] > Before, we used this to disable feature pinning, if I recall correctly. I'm not sure: at least in previous versions of the conffile shipped in the package, we commented out the features-file directive. apparmor_parser(8) says that --features-file requires an argument and "Config options are specified one per line using the same format as the longform command line options (without the preceding --)" so the behaviour you're observing, while maybe suboptimal, is the documented one. Can you try to reproduce on Stretch and sid? If behaviour has changed, it's a different matter :)
