Three options, each explained rather than named, because the difference between
them is a security posture and the default is the one that sounds harmless.
1 docker group, the default. The text says what the group actually is: anyone
in it can run `docker run -v /:/host -it alpine chroot /host` and have a root
shell. It is not "access to Docker", it is root by a longer route — the same
framing os-user-docker.ts already uses for why members never get it.
Whether that matters is conditional, and the run works it out rather than
asserting either way: on an account that already has sudo it is a shorter
path to something they can reach anyway, and it says so; on an account that
does not, it is a real escalation, and it says that instead. Caught in
testing, where the reassuring sentence was being printed for a throwaway
account with no sudo at all — the exact case where it is untrue.
2 rootless, with the thing nobody would find out stated at the prompt:
Officer's app store cannot provision containers with it. compose.ts,
preflight.ts and system-monitor all spawn `docker` with no environment of
their own, so they reach /var/run/docker.sock; DOCKER_HOST is set only for
member commands, in os-user-docker.ts. pm2 started at boot by systemd has no
session either, so exporting it in a shell rc does not reach the process
that matters. The consequence is recorded in the summary, not just spoken.
3 neither, and what that costs.
Also fixed in the port: the repository codename came from `lsb_release -cs`, which
is wrong on every derivative — Mint reports "vanessa", Pop reports its own, and
Docker publishes neither, so `apt update` fails against a repository that does not
exist. os-release carries UBUNTU_CODENAME on exactly those systems for exactly
this reason; it is preferred now, with VERSION_CODENAME as the fallback, and the
ubuntu/debian half of the URL comes from ID_LIKE rather than being hardcoded.
The shared `services` network is created only when missing, checked with
`docker network inspect` rather than by running create and discarding the error.
Verified on this host, and against a throwaway account both with and without
sudo.
