Cirrus-CI: Free FreeBSD CI testing for open-source projects

[Alan Somers]

Cirrus Labs has just released support for FreeBSD on their CI service.  And
they've made it free for OSS!  Cirrus-CI is a cloud-based CI system for
cloud-hosted software, much like Travis-CI, Appveyor, Circle-CI, etc.  But
it's the first* such system to support FreeBSD with no weird hacks
required.  It also runs each test in a full VM, so you can mount
filesystems, create jails, etc.  The free tier supports runs on a dual CPU
VM with 4GB of RAM.  But if that's not enough, you can cheaply configure
Cirrus to use a custom VM in Google Cloud (gcp account required; cheap but
not free).
