Operator watched /tmp/new.log through a claude mint and saw not one
message: cloud-init's progress dots are block-buffered the moment
stdout is not a tty, so a redirected mint shows nothing for the whole
install and then one burst — which reads exactly like a hang, on the
very night three real hangs happened.
PYTHONUNBUFFERED=1 on the cloud-init wait makes the dots arrive as
dots; box new also prints how to watch the box's own full narration
(incus exec <box> -- tail -f /var/log/cloud-init-output.log); and the
drill's logs are named for the box being minted (/tmp/mint-drill.log),
not for the verb that mints it.
Run 14: the blank mint — the FIRST VM launch on the fresh btrfs pool,
which unpacks the image into a pool volume and takes the coldest boot —
died at wait_agent's 3-minute window ('Processes: -1' well past it),
while the identical claude mint sixty seconds later booted in the warm
path and passed in 96s. The window was tuned on a dir pool with a
cached, unpacked image.
150×2s now, and on failure box new prints the VM's console log tail
before dying — this run's evidence was torn down with the box before
anyone could read it.
All four mints (blank, claude, clone, peer) now run through mint_box:
box new's narration lands in the log as before, the drill prints where
to tail it, and a dot every 5s on the drill's own terminal proves the
run is alive. A silent multi-minute mint is indistinguishable from a
wedge, and that ambiguity has cost whole evenings — the operator said
so, verbatim.
Run 14's second catch: the blank mint's cloud-init finished, printed
'status: done' — and 'box new' hung for 15+ minutes on an exec session
that never closed ('incus operation list' showed it still RUNNING).
With a TTY on stdin (the drill redirects only stdout/stderr), incus
exec goes interactive, and the session can wedge open after the remote
command has exited. Same disease as drill trap 2 and doctor trap 13;
the CLI's own execs never got the cure.
Every non-interactive exec now pins stdin: wait_agent's probe, the
cloud-init wait, both failure-path reads, and the clone identity
reset. shell/exec/tmux keep the terminal — owning it is their job.
Also: wipe.sh keeps cached images on a plain wipe. An image is
upstream's artifact, content-addressed by fingerprint — deleting it
buys zero cleanliness and costs the next mint a full re-download. It
goes only with --purge-storage, where the pool it lives in goes too
(and it must go first: images block pool deletion).
The profile rename changed the file's name, header and limits but not
the device's 'network:' field; the claudenet→boxnet sed covered
host/*.sh only. On a wiped host (no claudenet to silently latch onto)
'incus profile edit box-net' refused the YAML and setup died — run 14's
first catch, before a single box was minted. The sweep this fix rode in
on found exactly one other stale reference, in the same file's comment.
Follow-up to the rename, per operator direction — the divergence is
reversed and the cut is complete:
- Host stack: boxnet (10.88.0.0/24 — a pre-rename host may still carry
claudenet on 10.87, two bridges must not claim one subnet),
box-isolate, nft tables 'inet box'/'bridge box', box-firewall.{sh,
service}. teardown-host now strips BOTH name generations, so one
script uninstalls a host of any age.
- Default template is blank: 'box new --name x' mints bare Debian;
the claude box is '--template claude'. The login hint follows the
EFFECTIVE template read off the instance, so clones of claude boxes
still get it and blank boxes are not told to run a binary they lack.
- The drill validates templates: listing, unknown-template refusal,
the allowlist rejecting BOX_NETWORK by name, and a full blank mint —
default resolves to blank, metadata stamped, box-net placement, exec
lands in 'dev', no claude binary, and isolation parity (egress +
pinned DNS) on the same contract as every template.
- drill/wipe.sh: scorched earth for drill hosts. Both tag generations,
every drill-named instance, networks/ACLs/profiles/firewall of both
generations, cached images, and (--purge-storage) the default pool.
Ends by asserting the ABSENCE of every artifact rather than trusting
the removals' exit codes.
The tool underneath was already generic: a thin, honest wrapper over
Incus. What was Claude-specific was welded on — one image, one profile,
one cloud-init file, one hardcoded 'sudo -u claude'. The weld is now a
template.
The mechanic: 'box new' stamps the template's identity onto the
instance (user.box=1, user.box.template, user.box.user); shell/exec/
tmux read the user back off the instance, and 'incus copy' carries
user.* keys (audit B2), so a clone knows what it is without consulting
the template. Templates are box.env (parsed against a strict allowlist,
never sourced — no key for a network exists, on purpose) plus a
verbatim cloud-init. Every template launches with the shared box-net
profile: the isolated NIC and root disk, nothing template-controlled —
resources land per-instance from box.env, overridable via BOX_CPU/
BOX_MEMORY/BOX_DISK (which is also how the drill shrinks boxes on a
small host now that profile edits can't).
The three open calls, taken as recommended: clean cut at 0.4.0 (no
claudebox shim; the installer retires the old symlink); default
template = claude (muscle memory survives); repo stays heavy-duty/
claudebox, binary is box.
Compat is the tag, not the name: resolve_box and list honor the legacy
user.claudebox=1 forever, and the legacy tag maps to the claude user —
a pre-rename box lists, shells, clones, unchanged.
Deliberate divergence from #17's table: the host-stack resource names
(claudenet, claude-isolate, nft tables, claudebox-firewall.*) are NOT
renamed — they are host-internal, invisible to users, and renaming
them breaks every provisioned host for zero user-visible gain.
claude-dev is no longer created; setup-host creates box-net, teardown
removes both.
Closes#17
