Comment 7 for bug 1892306

Hi Karl,
glad I could help with that.

The change is part of a bigger series that needs to drop a apparmor reload, change the way AppArmorSetSecurityImageLabel is called and only then finally can use the append functionality in this case.

The SRU [1] policy is rather strict on avoiding potential regressions for existing users (or at least need to be tremendously outweighted by the gains in rare cases) and this could have unwanted side effects. Furthermore the willingness to risk that reduces for cases like this where
 a) you'd have the option to slightly change the use-case to get it working and
 b) there already is an active Ubuntu LTS released that fixes the issue

So I'm inclined to say no I won't backport it to Bionic unless there is a stronger reason/need to do so.
