Why: disinto_init() consumed $1 as repo_url before the argparse loop ran,
so `disinto init --backend=nomad --empty` had --backend=nomad swallowed
into repo_url, backend stayed at its "docker" default, and the --empty
validation then produced the nonsense "--empty is only valid with
--backend=nomad" error — flagged during S0.1 end-to-end verification on
a fresh LXC. nomad backend takes no positional anyway; the LXC already
has the repo cloned by the operator.
Change: only consume $1 as repo_url if it doesn't start with "--", then
defer the "repo URL required" check to after argparse (so the docker
path still errors with a helpful message on a missing positional, not
"Unknown option: --backend=docker").
Verified acceptance criteria:
1. init --backend=nomad --empty → dispatches to nomad
2. init --backend=nomad --empty --dry-run → 9-step plan, exit 0
3. init <repo-url> → docker path unchanged
4. init → "repo URL required"
5. init --backend=docker → "repo URL required"
(not "Unknown option")
6. shellcheck clean
Tests: 4 new regression cases in tests/disinto-init-nomad.bats covering
flag-first nomad invocation (both --flag=value and --flag value forms),
no-args docker default, and --backend=docker missing-positional error
path. Full suite: 10/10 pass.
