+# Why we put the /snap/microk8s/current in the path?
+# containerd-shims need to call runc. They inherit their PATH from containerd.
+# As the snap refreshes runc changes location, eg moves from
+# /snap/microk8s/123/usr/bin/runc to /snap/microk8s/124/usr/runc.
+# containerd-shims need to look for runc in  /snap/microk8s/current/usr/bin/runc
