[meta-virtualization] [PATCH 6/6] podmon: add the Pod Manager tool

[Bruce Ashfield]

I'm assuming the subject should be "podman" and not "podmon".

On my other similar recipes, I've been asked to make this a ?= so it
can be easily overridden. Is that possible here ?

Is this a debug statement left in, or is it relevant to podman ?

I've been trying to squash out all the raw calls to make. Does this
work if oe_runmake is used ?

Also, out of curiosity, if GO=go isn't set .. what executable does it
try to run ?

Same here. Does oe_runmake work ?
