box/host/teardown-host.sh
dan-claude-bot 9d3ca92ffa feat(cli): versions, use, uninstall — the install managed from the CLI, absence-asserted
'box versions' lists what is installed (current + running marked); 'box use'
flips the default, refuses under existing boxes (#66), and asserts the
EFFECTIVE result — current resolves to the version asked for and the chain's
own --version answers it. 'box uninstall' is the real uninstall the old
two-rm-rf-lines of prose never were: one version, or everything in the safe
order (boxes first — refuse or --purge-host — then trees and symlinks), and
it ends by re-checking every promised path is gone, exiting 1 naming
leftovers (the revoke --purge discipline). teardown-host grows --yes/BOX_YES
for the unattended paths and points at 'box uninstall'; the drill reads the
installed tree through current/.

# Reverse everything host/setup-host.sh created — and everything its pre-0.4.0
# ancestor created, so one teardown cleans a host of any generation: all boxes
# (both tags), the boxnet/claudenet networks + ACLs, the box-net/claude-dev
# profiles, and both generations of firewall units and nft tables.
# Usage: ./host/teardown-host.sh [--purge-incus] [--yes]
# --purge-incus also apt-purge Incus itself (skipped if non-box
# instances still exist on this host)
# --yes skip the confirmation (BOX_YES=1 does the same) — for
# automation: CI's uninstall drill and 'box uninstall
# --purge-host' run this unattended
