Production User Calls
Meet with production users every week who rely professionally on:
- Jails and Zones - Agenda / Minutes
- OpenZFS - Agenda / Minutes
- The bhyve hypervisor - Agenda / Minutes
Thank you Prominic.NET for providing monthly funding for these efforts and at around 100 calls that can run up to three hours, every bit of support helps.
FreeBSD Build Option Survey Results
These Build Option Survey Build Results have quietly been the most active content on this site through the pandemic. They represents builds of several FreeBSD branches loosely tracking the Release Engineering weekly snapshots.
The official FreeBSD Build Option Survey (BOS) is extremely time consuming.
"BOS Lite" uses an OccamBSD script to exclude all options, providing the bare-minimum OS build, which conveniently exercises the majority of FreeBSD build options.
Making all FreeBSD build options work by the 13.0 release was a multi-year effort involving several people and there have been very few regressions.
FreeBSD History Rebuild
This spreadsheet describes the status of FreeBSD release ISOs that are not available at ftp-archive.freebsd.org. If you have any of these historic releases obtained by FTP download or Walnut Creek CD-ROMs, mail Michael confirmation of your checksums and post missing images. Thank you for your help!

Welcome to Call For Testing, an online technical journal dedicated to the Berkley Unix. Call For Testing picks up where other BSD-related publications leave off by providing:
- Authoritative BSD technical information that aims to document, analyze and inspire
- In-depth BSD conference reporting for those unable to attend
- Unbiased analysis of BSD business and community management issues
- Community outreach and coordination involving developer hardware acquisition, event organization and formal advocacy
- Actual calls for testing of new code to help guarantee that the BSD's remain "The greatest software ever written." (Information Week, August 2006)
- Ultimately, a platform for educating and orienting the next generation of BSD developers
