The lint CI runs pre-commit on changed files, so touching these scripts
surfaced pre-existing warnings. Address them without changing behavior:
- Quote array elements (SC2206) and command substitutions (SC2046).
- Disable SC2087 on the ssh heredocs (vars are intentionally expanded
client-side) and SC1090 on 'source ~/.bashrc' (not followable).
- Keep unused config knobs (KVVERSION, interface) with a targeted
SC2034 disable; drop the genuinely-unused allnomaster1 array.
- Strip trailing whitespace.
Verified: shellcheck --severity=warning clean and pre-commit green
(ShellCheck v0.10.0) on both files; bash -n syntax OK.
The wait-loop was missing '-o' before the jsonpath template, so
'jsonpath={...}' was parsed as a service name and the query errored
to empty output, causing the loop to never wait. It also queried
.status.conditions[Pending], a shape Services do not have.
Poll the rancher-lb service and block until MetalLB assigns an
external IP instead.
