I wouldn't call it an in-house solution since the package target is a
feature of the ports infrastructure.  We simply 'make package' and
install other systems from the resulting package.

This does not, however, appear to be as well supported by portsng/pkgng
as it was in the previous versions.  Now it just exits with no message
and a 0 exit-code without creating the package unless you've created
/usr/ports/packages and/or specified one or more of WRKDIRPREFIX,
PACKAGES and PKGREPOSITORY.

What documentation there is seems to be based on older versions (like
much of the FreeBSD website) and I haven't found anything on the
differences between 'make package' and Poudriere.
