which with remote Ohai doesn't seem to work as expected

[tas50]

The Network plugin has a check to see if the ip command exists:

if which("IP")

if this fails it falls back to route and executes:

shell_out("route -n")

When remote ohai is run against a Unifi UDM Pro:

It's clearly failing to find the IP command which is there:

# which ip
/sbin/ip
