I have set up a pkg_comp chroot, and inside I run pkg_chk -rvk to remove "mismatched" (outdated) packages, and then pkg_chk -vak to rebuild everything that was removed. In between I have a home grown script that moves aside the binary packages that were de-installed, to make sure that they get rebuilt even if the version is not increased. It basically corresponds to the unsafe_depends flag from pkg_rr. It also generally deals well with renamed packages and such restructuring. I find that this method generally leaves a lot of packages installed, but also those are typically not the ones that take longest to build. From about 1250 packages in my directory, about 300 are still from early October, when I rebuilt everything because (I think) I updated the chroot to 8.1. or changed gcc version or similar. -Olaf. -- Olaf 'Rhialto' Seibert -- rhialto at falu dot nl ___ Anyone who is capable of getting themselves made President should on \X/ no account be allowed to do the job. --Douglas Adams, "THGTTG"
