That we do! We package various FreeBSD stuff for Debian GNU/kFreeBSD and then build some of it reproducibly already. We already have in Debian - on kfreebsd and linux - the necessary toolchain packages such as clang-3.4, bmake, freebsd-mk, freebsd-buildutils and particular versions of byacc and flex. We prepend "/usr/lib/freebsd:" to $PATH in order to use these: https://anonscm.debian.org/viewvc/glibc-bsd/trunk/kfreebsd-10/debian/rules?view=markup#l46 We were actually able to build our package of the FreeBSD kernel on GNU/Linux, and the binary would match what we built on GNU/kFreeBSD. (Which I think is the ultimate in securing against attacks on the build/development systems). I haven't tried building much else from FreeBSD - on Linux, or on GNU/kFreeBSD - using only FreeBSD's original build system. In our packaging we tend to make changes as necessary to get individual bits to build. I understand wanting to do this on GNU/Linux, but if that's too difficult, it may be easier trying this in a chroot on GNU/kFreeBSD first. You can even run a Debian GNU/kFreeBSD host system with native FreeBSD binaries inside a chroot or jail, potentially a whole native build system inside of it. In any case, I'd like to someday see a GNU/kFreeBSD machine set up as a http://jenkins.debian.net slave, doing rebuilds and alerting us if any packages in sid are FTBFS, as well as other tests. > There may also be a better mailing list for this... Discussions are very welcome on debian-bsd@lists.debian.org, although we are rather busy this week finalising a jessie-kfreebsd release. Regards, -- Steven Chamberlain ste...@pyro.eu.org
