But see below for why we might have to change the subject even
further.

I think something like

  The base OS image might include outdated contents, and we don't
  want to get spurious failures caused by bugs that have already been
  fixed in the respective packages.

  This is particularly important on macOS, because 'brew install foo'
  will fail if 'foo' is already installed but outdated: upgrading all
  packages first ensures we never run into this scenario.

would about sum it up.

I believe you also need to add

  UPGRADE_COMMAND: pkg upgrade -y

to the FreeBSD jobs: I don't think Cirrus CI would appreciate having
a completely empty string in the list of commands it's supposed to
run.

With that squashed in,
