I'm just running from a clue by bapt@ and what's on the release DVD, in which case the ALTABI form is a symlink: freebsd:12:x86:64 -> FreeBSD:12:amd64 and the All packages directory is packages/FreeBSD:12:amd64/All: total 2204897 > How/When does pkg decide to use FreeBSD:13:amd64 instead of > FreeBSD:13:x86:64? Can I safely assume one or the other? You can safely assume the former, that's the usual form. The ALTABI form _might_ be safe but I've not tried using it. cheers, Ian (not subscribed to ports@)
