Actually the metadata should be in the package, rather than the repository. We need to record the OS version the package was compiled under at the point the package is created, and then pkg(8) can compare that to the OS version at install time. This will work not just for the FreeBSD pkg repos, but for packages built for private repos too. And it will still work, even if you grab a bunch of packages from somewhere else and make your own repo from them. Even so, pkg(8) should not refuse to install the newer package on the older system; just emit a big fat warning that what you're doing is dangerous, and may lead you into regret and grief. (Unix has a tradition of not stopping users from doing stupid things, because that also makes it possible to do amazingly clever things...) This is complicated by such things as 'NO_ARCH' packages -- your pure perl/ruby/python code is still going to work almost regardless of the OS version. As will all sorts of type fonts or collections of desktop icons and so forth. Plus this will need to be carefully debugged when packages are cross-compiled or compiled in jails on a host system with a different kernel version.
