apparmor_parser
Integrity and confinementPackage: apparmor
Loads, reloads or removes an AppArmor profile. apparmor_parser -r reloads a changed profile without restarting the service it confines — the command you want when a service is allowed to write a file and AppArmor refuses it.
What its options do in the lessons
From the same glossary the lessons render under their commands, so the two cannot disagree.
apparmor_parser -r- Reloads a modified AppArmor profile into the kernel. Without the reload the old version stays in force, and a freshly added rule appears to do nothing.
