This all happens fairly quickly at the beginning where poudriere is working out what work it needs to do. Basically poudriere takes a copy of the repo[*], deletes from it everything that needs rebuilding (out of date, options changed, etc.) and then removes everything that itsself depends on a removed package. Then it takes the list of packages you give it which you want to have in the repo, expands the list to include all of the dependencies those packages require to both build and run and then generates all of the packages that currently are missing from the repo. This actually does do quite a bit more work than is strictly necessary -- poudriere deliberately errs on the side of caution in order to ensure that the generated repo is completely self consistent. 'poudriere bulk -c' just elides the step of working out what needs updating and starts with an empty repository, so building every package you need in order to produce the packages you want. This also means that (if you choose the options in pkg.conf appropriately) that you can keep older revisions of a pkg repo around, which you can revert to if you need it. Cheers, Matthew [*] Loosely "copy" in that it make links to the existing packages from previous builds, so being rather more space efficient than literally copying the packages every time. --cr6GU0EtidwTm9VNQo54liwjhvX8PdLCq-- --oklvcNUgTgoNrxFMkkNFNRFCqSEdUEa8Q Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQJ8BAEBCgBmBQJYjGsGXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NTNBNjhCOTEzQTRFNkNGM0UxRTEzMjZC QjIzQUY1MThFMUE0MDEzAAoJELsjr1GOGkATkP0P/A9pbb9qj1XccB0x9+myyj1e VHGr7D2Jl3pKhEg8WC28V3HbvEQy0WaZoXtN8S4DvKY15gAb5CYC6rXAC1qTryVp MZ87d0G3TaVgVtfMO5pOKWL6imT56F35Yhu8Gsf4+TfslY7f1zZkA2LDREYuFGjR XDgeD9z6VFAsSMU8L5HSGW2Z7egYkRhICCBgxnAYshDH1BtB6pC+tbg8zooMP7R6 5Mm5xHgfuKoEniWP+09rlYf1pieVJSGdKgWXH0dgLvhBYn6rR1MmHDHjkFnUA4h2 vKDsoBjSw8ak1uwQjZWo0yd5DrbdiwVERnFuIpG2c81hChegPyOs33lJ8JP/7tWQ gHn/dumFzwKNhfXQbIp6Q7lW+xO+9mRDtQRzsS92bP+0ghe9KPaFiQjRhgwzaQWw HsVmjIwdqfRzQ2sdpSqyzz+3d6cx1eRsk5p7D0kQLVejFO4WBER5z5WXvh43hIAM gmFw+EL43W69AWXX+8yrY0LoJzavR77QQRpQeRSFYImku54La+qlyAVFkSl41d/Z Vb+jU+0WLzVXugC9jMr+Ke3R9kxs2RBIiOL4StuvH9bj5tS6eRGB4vRZE9t2hnX9 jFl9ka9Amvm51FhYdvauYxle2zmM3QFxxEcbil9Si5rufAGQXITFLRRVH/OXEFNa h2DEofYVc2eu532N9HZ9 =eHqO -----END PGP SIGNATURE----- --oklvcNUgTgoNrxFMkkNFNRFCqSEdUEa8Q--
