While I think custom poudriere builds were in use, the main problem is
users that fail to quickly update to the newest OS release have issues
when installing official pkg updates which break a machine in use.

Without installing a pkg there is no way to know if it will run or
break. A pkg manifest records it's abi as FreeBSD:11:amd64 which doesn't
tell you that it will fail to run on an 11.1 system. There is also no
way to specify a pkg repo path that prevents you getting broken pkgs.
