We have not had any feedback on this yet and want to get it enabled by
default for ports and packages.

We now have a repository that you can use rather than the default to
help test. We need your help to identify any issues before switching the

This repository is available for:


It is not available for 8.4. If someone is willing to test on 8.4 I will
build a repository for it.

Place this in /usr/local/etc/pkgs/repos/FreeBSD_ssp.conf:

FreeBSD: { enabled: no }
FreeBSD_ssp: {
  url: "pkg+http://pkg.FreeBSD.org/${ABI}/ssp";,
  mirror_type: "srv",
  signature_type: "fingerprints",
  fingerprints: "/usr/share/keys/pkg",
  enabled: yes

Once that is done you should force reinstall packages from this repository:

  pkg update
  pkg upgrade -f

Thanks for your help!
