Two boxes cloned from one snapshot came up holding the SAME IP address — 10.87.0.128, on the same dnsmasq lease, matching to the second on the lease timer. Incus does regenerate the MAC (they differed), but /etc/machine-id rides along inside the disk image, and systemd derives its DHCP client identifier from it. Same client-id, same lease. This breaks the workflow claudebox exists for: log in once, snapshot, clone forever. Every clone of a snapshot is, to the network, the same machine as its source and as its siblings. Truncating /etc/machine-id makes systemd mint a fresh one at next boot, so the clone path now resets it and restarts before handing the box over. Costs one reboot; the alternative is colliding boxes. Found by the drill on a live host (#26) — and it also explains why the sibling-isolation probe (#15 A3) could never work: it was aiming box A at box A's own address.

|
|
--from <src>[/<snap>] Clone from box <src>, or from its snapshot (new)
|
|
--vm Force VM mode: the trust-less target (new)

EXAMPLES
|
|
# mint a box and log in inside it — the tool never handles your token
|
|
claudebox new --name work
|
|
claudebox shell work # then: run 'claude', then /login
|
|
|
|
# log in once, reuse forever: checkpoint the authed box, clone from it
|
|
claudebox snapshot work authed
|
|
claudebox new --name feature --from work/authed
|
|
|
|
# what have I got, and what can I clone?
|
|
claudebox list
|
|
claudebox info work
|
|
|
|
# run something without opening a shell
|
|
claudebox exec work -- git -C project pull
|
|
|
|
# anything claudebox doesn't wrap: boxes are plain Incus instances
|
|
claudebox incus work -- config show
|
|
|
|
EXIT STATUS
|
|
0 ok
|
|
1 it went wrong (Incus failed, no such box, aborted at a prompt)
|
|
2 you asked wrong (unknown command, bad flag, destructive act without --force)
|
|
|
|
THE MODEL
|
|
A box carries NO credentials. You authenticate interactively inside it
|
|
('claude' then /login; 'gh auth login'); claudebox never stores or injects a
|
|
secret. A box reaches the public internet and nothing else — there is no
|
|
inbound path. Destroying a box loses nothing you didn't push.
|
|
|
|
claudebox owns a command when it must enforce something Incus cannot see: the
|
|
user.claudebox=1 boundary, the isolation stack, or the creds-free snapshot
|
|
workflow. Everything else is Incus's job — and 'claudebox incus' is the door.

Mint a box. Without --from, launches a fresh Debian 13 box from cloud-init
|

(~10 min cold) with Claude Code installed and NO credentials. With --from,
|

clones an existing box or one of its snapshots — Claude login, git creds and

clones carry over, isolation is preserved.
|

|
|
--name <box> Required. The box's name.
|
|
--from <src>[/<snap>] Clone src's live state, or its snapshot <snap>.
|
|
--vm | --container Force the mode. VM is the trust boundary and the
|
|
default wherever /dev/kvm exists; container mode
|
|
(security.nesting=true) is the fallback for hosts
|

without nested virt — weaker isolation, dev/test only.

|
|
Takes no box — for one box, that's 'claudebox info <box>'.
|

|

--json Incus's JSON, straight through, for scripting.

info) cat <<'EOF'
|

Show one box: state, type, IP address, and — the reason this exists — the
|
|
labels of its snapshots, with the --from line to clone one.
|
|
|
|
--json Incus's JSON, straight through, for scripting.
|
|
|
|
claudebox info work
|
|
EOF
|
|
;;
|
|
shell) cat <<'EOF'
|
|
Open an interactive shell in a running box as the 'claude' user. This is the
|
|
only entry path — there is no SSH and no inbound route to a box.
|
|
|
|
claudebox shell work
|
|
EOF
|
|
;;
|
|
exec) cat <<'EOF'
|
|
Run a command inside a box as the 'claude' user. Everything after -- is passed
|
|
through untouched; the -- is required, or claudebox will read your command's
|
|
flags as its own.
|
|

claudebox exec work -- git -C project pull
|
|
claudebox exec work -- claude --version
|
|
EOF
|
|
;;
|
|
snapshot) cat <<'EOF'
|
|
Checkpoint a box. Snapshots are how an authenticated box is reused: log in
|
|
once, snapshot, then 'new --from <box>/<label>' as often as you like. The
|
|
label defaults to manual-<epoch>; 'claudebox info <box>' shows the labels you
|
|
have.
|
|
|
|
claudebox snapshot work authed
|
|
EOF
|
|
;;
|
|
restore) cat <<'EOF'
|
|
Roll a box back to one of its snapshots, in place. Anything in the box since
|
|
that snapshot is lost. 'claudebox info <box>' lists the labels.
|
|
|
|
claudebox restore work authed
|
|
EOF
|
|
;;
|
|
rename) cat <<'EOF'
|
|
Rename a box. Incus cannot rename a running instance, so stop it first:
|
|
|
|
claudebox down work
|
|
claudebox rename work archive
|
|
claudebox start archive
|
|
|
|
Snapshots and Claude auth follow the box; anything referring to the old name by
|
|
hand (a --from line, a script) does not.
|
|
EOF
|
|
;;
|
|
rm) cat <<'EOF'
|
|
Delete a box and every snapshot it has. This cannot be undone, so it asks for
|
|
confirmation first; --force (-f) skips the prompt. With no TTY to confirm on
|
|
(a script, a pipe), it refuses unless --force is given.
|
|
|
|
claudebox rm work
|
|
claudebox rm work --force
|
|
EOF
|
|
;;
|
|
incus) cat <<'EOF'
|
|
The door out. claudebox wraps the box lifecycle and the isolation model, not
|
|
all of Incus — so when you need something it doesn't wrap, run Incus through
|
|
here and keep the safety rail that matters: the box name is resolved and
|
|
checked against the user.claudebox=1 tag, so you cannot aim it at an instance
|
|
claudebox didn't mint.
|
|
|
|
Everything after -- is passed to incus verbatim. A literal {} is replaced with
|
|
the resolved instance name; with no {}, the instance is appended at the end.
|
|
The command that will run is echoed before it runs.
|
|
|
|
claudebox incus work -- config show
|
|
claudebox incus work -- config device add {} extra disk source=/data path=/data
|
|
|
|
Changing the profile, the network, a device or a security.* key can take a box
|
|
outside the isolation stack. claudebox warns and then does as you asked — from
|
|
there, the trust boundary is yours to keep.
