Poudriere make.conf documentation question

[Jose Quinteiro]

Hello,

The Handbook says:
"The system make.conf and this new file are combined at build time to
create the make.conf used by the build jail."
https://www.freebsd.org/doc/handbook/ports-poudriere.html

The poudriere man page and Porter's Handbook do not mention
/etc/make.conf as a file that will get used.

My simple test did not work with /etc/make.conf, but I also suspect I
screwed something else up.

Does /etc/make.conf get "combined" into the effective make.conf for
Poudriere?

Thanks,
Jose
