permissions warnings for fn start from https://github.com/fnproject/fn

Question

Are these permission warnings fixable when starting Fn github project locally on my Docker in Docker (dind) instance following the directions on the github project: https://github.com/fnproject/fn ? I installed via brew on a mac.

$ fn start
mount: permission denied (are you root?)
Could not mount /sys/kernel/security.
AppArmor detection and --privileged mode might break.

Some of those warnings/messages are MacOS specific (ie: you won't see them on Linux). But they won't affect regular operations so you can safely ignore them.
