With all due respect, this is quite different from what I know about poudriere. And the difference is in the fact that poidriere builds everything in jails. Therefore, here is what I have (Note, that all my machine run RELEASE):

1. host system is the highest version of the RELEASE
2. for poudriere buld the same major/minor versions RELEASE jails are created, collections of packages for each minor/major version is built in jail the base of which is exacly the same as minor/major version as the system you build packages for.

In other words, Matthew, you don’t need to have separate host running FreeBSD 11.3-RELEASE, packages for FreeBSD 11.3-RELEASE can be build on  FreeBSD 12.1-RELEASE in jail which has base FreeBSD 11.3-RELEASE

That is the beauty of pouderiere, it is designed to have everything built on one machine.

So, here is what my poudriere box is today:

host system: FreeBSD 12.1-RELEASE


jails packages are built in have base system as the machines packages will be installed on:

Jail1: FreeBSD 12.1-RELEASE
Jail2: FreeBSD 12.0-RELEASE
Jail3: FreeBSD 11.3-RELEASE
…

The simple explanation why it is appropriate is: when built in jail everything is as on the system of level the jail base is, so appropriate libraries are linked etc.

The necessity to run highest version on pourdiere host stems from the fact that you can not run jail of higher version than that of host system.

I hope, everything is clear now.
