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=E2=80=99t 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 =E2=80=A6 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. Valeri > Thus a 12.0 poudriere machine can be used to maintain packages on a = mix > of 12.0, 12.1 and 12-STABLE machines.
