The container still exited immediately after the su-based fix. can
interfere with TTY/stdin handling for interactive shells. Switch to
, which is root-only, skips PAM, and preserves file descriptors so
bash stays interactive.
Also improve container failure diagnostics:
- now combines stdout and stderr
- This helps surface the real reason when a container exits with code 0
Quality gates:
- pytest tests/unit: 219 passed
- ruff: clean on changed files
- mypy: clean on changed files
- Switch apply_resolved_profile from per-file bind mounts to one
directory-level bind mount per ResolvedMount target.
- Stage all configured files under instance_dir/mounts/<sanitized_target>
and bind-mount that directory, so Docker no longer creates a root-owned
parent directory such as ~/.config.
- Propagate read-only mode ('ro') as the 'readonly' flag on volume entries.
- Update unit tests to expect directory-level mounts and add coverage for
readonly/writable flags.
