A host=yes box exists to run guest boxes, so bootstrap finishes the job
instead of printing "next: install the box CLI and run 'box setup-host'".
After the role marker is written, on host=yes it installs the box CLI
globally and lets box's OWN setup-host build the Incus stack.
rig DELEGATES to box; it never touches Incus itself — the same design law
`rig users apply` enforces ("rig NEVER installs Incus: box's setup-host
owns the daemon and its group"). rig does not apt-install incus, does not
configure the daemon, does not create the incus group. It runs box's global
installer as root with BOX_YES=1 (non-interactive AND keeps setup-host);
box installs Incus. Two tools converging one daemon is drift by construction.
- Convergent: box's installer is a no-op once box is installed, so re-running
bootstrap changes nothing.
- Opt-out: RIG_SKIP_BOX_INSTALL=1 skips; also skips gracefully (with a manual
pointer) when curl or the network is missing — box is the host EXTRA, so a
failed box install never aborts a bootstrap that otherwise succeeded.
- Pinnable: BOX_REPO / BOX_REF (default heavy-duty/box@main).
- Runs only AFTER the role marker write, so a box that failed to become what
it claims never installs box on a half-built host.
The world-readable global install path (box under /opt/box, readable by every
non-root user) depends on box PR #71; until it merges box's root install lands
in /root. Noted in a comment and the plan doc.
Completes rig#12 (the dev role — the Incus claudebox host) and rig#25
(machine classes: host-class installs box + rig users).
Tests: 8 new bootstrap checks (guard on host=yes, BOX_YES install, pin
defaults, RIG_SKIP_BOX_INSTALL opt-out, negative-grep that rig never
apt-installs incus, box-after-marker ordering, manual-pointer on skip).
154 passed, 0 failed; shellcheck -x clean.
