Comment 6 for bug 1260103

For current (click) apps on the phone, the APP_PKGNAME variable is used to parametrize apparmor policies. According to https://wiki.ubuntu.com/AppStore/Interfaces/ApplicationId, this is the name of the click package (e.g. "com.ubuntu.foo"). However there are currently no existing rules to allow /{dev,run}/shm/*${APP_PKGNAME}*, so apparmor-easyprof-ubuntu would need to be updated to add such a rule.

I’m fine with using PathService, but that will result in a slightly more intrusive patch to chromium. I think I’d rather rely entirely on environment variable, rather than adding a command-line option.
