Hey Julian, I've thrown the patch up at https://reviews.freebsd.org/D12330 . I haven't actually tested it on FreeBSD, but it does compile. We also have some patches against contrib/pjdfstest to fix those tests against long file names, but I think we can hold off on those changes until we've nailed down what the architectural change will be (if any). It's quite possible this accidentally breaks even more APIs than expected and we should do some fine tuning to reduce the damage. Our $WORK product mostly doesn't care about ABI, so we may not have noticed some ABI breakage. If anyone else is interested, please subscribe or add yourself as a reviewer on the phabricator revision. Best, Conrad
