Description

AppArmor 2.13-7 will “parser.conf: turn off expression tree simplification, that makes performance much worse in some cases”, which I think will introduce a boot time regression for Tails. We should measure that and if indeed it is a regression, revert this `/etc/apparmor/parser.conf` patch in Tails.
