lima-actions fails with freebsd-15 image w/o xorriso pre-installed

[kolyshkin]

When trying to run freebsd-15 VM in GHA I saw this error:

time="2026-05-27T07:37:46Z" level=info msg="Resize instance default's disk from 6.033GiB to 100GiB"
time="2026-05-27T07:37:47Z" level=error msg="[hostagent] none of [xorrisofs genisoimage mkisofs] is available" fields.level=fatal
time="2026-05-27T07:37:47Z" level=fatal msg="host agent process has exited: exit status 1"

(from https://github.com/godbus/dbus/actions/runs/26497604586/job/78029558406?pr=420)

I tried adding with: additional_guestagents: true but it didn't help.

Had to add the following step before lima-action to resolve this:

 - name: Install xorriso (needed by lima to create cloud-init ISO)
   run: sudo apt-get update && sudo apt-get install -y xorriso

which is sub-optimal because lima-actions also does apt-get update && apt-get install.

Perhaps some action option can be added (extra_packages with a list, or merely boolean), or xorriso can be installed by default?

xorriso can be installed by default

FreeBSD is rarely used today, and the dependency on xorriso is expected to be removed eventually, so I don't think we should do it.
