poudriere and ports overlay support

[Miroslav Lachman]

I would like to try Overlay support in ports tree (announced few weeks 
ago in 2019Q4 branch).
The question is will it work with Poudriere or not? We are building all 
our packages with poudriere.

I tried adding OVERLAYS= /vol0/poudriere/ports/myports in to 
myports-make.conf but "poudriere options -z myports -p default -f 
/usr/local/etc/poudriere.d/pkglists/myports" failed when it reaches the 
<category>/<portname> existing only in myports and not in default ports 
tree.

Am I doing something wrong or Poudriere does not support Overlays?

Kind regards
