Is it safe to edit the addon manifests?

Hi. I’d like update some of the addon manifest configurations. The README mentions:

You can find the addon manifests and/or scripts under ${SNAP}/actions/, with ${SNAP} pointing by default to /snap/microk8s/current

Indeed, i do find the manifests at that location. I’m entirely unfamiliar with snaps, can anyone confirm:

  • is it safe to edit the manifest files at location /snap/microk8s/current/actions? will a future microk8s upgrade overwrite these files?
  • how do i reload an addon after updating the manifest file? do i just run microk8s disable addon && microk8s enable addon?
