NVIDIA OpenShell v0.0.116 openshell sandbox exec no-login-shell option source
💡 Result:
In NVIDIA OpenShell, the --no-login-shell flag is a command-line option available for the openshell sandbox exec subcommand [1][2]. It is used to execute a command within a running sandbox without sourcing the user's shell login startup files (such as.bash_profile,.bash_login, or.profile) [1]. By default, openshell sandbox exec runs commands through a login shell (bash -lc), which automatically loads tool-specific environment configurations [1]. Using the --no-login-shell flag prevents these startup files from executing, which is recommended for automation, managed checks, or scenarios requiring predictable output and side effects [1]. When this flag is used, the command still runs under bash -c, which may still read BASH_ENV if it is set in the command's environment [1]. This feature was introduced to address the need for non-interactive command execution without the overhead or configuration side effects of a login shell [1][3]. It is part of the openshell sandbox exec functionality, which allows for executing one-shot commands inside a running sandbox [1][4]. The flag is documented in the NVIDIA OpenShell management documentation [1][2].

Use an OpenShell CLI that supports --no-login-shell.
The runtime passes --no-login-shell to openshell sandbox exec, but NemoClaw pins OpenShell CLI 0.0.116, whose SandboxCommands::Exec parser does not define this option. The command can therefore fail with an unknown-option error before the advisor starts. Pin a compatible CLI release, or remove the option if login-shell behavior is acceptable.

## Outcome Managed workflow agents again execute commands with the pinned OpenShell 0.0.116 release. The shared helper no longer passes an unsupported option as command data, and restrictive policies permit only the pinned image's read-only shell startup files. ## Reason OpenShell 0.0.116 predates `sandbox exec --no-login-shell`. Its trailing command parser accepts that unknown option as the remote command, which makes Bash exit with `/bin/bash: --: invalid option`. This replaced the earlier startup-file denial after #11590 and stopped every PR Review Advisor specialist before it could run. ## Changes - Remove the post-release `--no-login-shell` option from the shared OpenShell 0.0.116 exec helper. - Permit read-only access to `.profile` and `.bashrc` in the Advisor and post-merge review policies. The conflict-fixer and author policy already permits `/sandbox`. - Assert that the Advisor command starts immediately after the OpenShell `--` boundary and cannot absorb the unsupported option. ## Verification - `npm exec -- vitest run --project integration test/automation/pull-requests/pr-review-advisor-openshell.test.ts test/automation/pull-requests/pr-merge-conflict-fixer.test.ts test/generation/post-merge-docs.test.ts --testTimeout=60000` — 124 tests passed. - `NODE_OPTIONS=--max-old-space-size=8192 npm run validate:pr` — passed after rebasing onto canonical `main`. - Inspected the pinned Advisor image without network access — `/sandbox/.profile` and `/sandbox/.bashrc` are image-owned 0644 files; the restrictive policies grant read-only access. - Reviewed the final diff; it contains no secrets, API keys, or credentials. ## Review notes This change affects managed remote execution. Credential stripping, command input validation, read-only host mounts, hard-required Landlock enforcement, sandbox cleanup, and failure propagation remain unchanged. The two newly readable startup files come from the digest-pinned image and remain non-writable under the restrictive policies. --- Signed-off-by: Julie Yaunches <[email protected]> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Security** - Updated sandbox access policies to explicitly include approved shell startup files as read-only resources. - Documented ownership and handling of sandbox initialization files. - Ensured post-merge review runs use the repository’s trusted policy configuration. - **Tests** - Expanded validation of sandbox startup and shutdown behavior, including signal handling. - Added checks for policy restrictions, command boundaries, supported and unsupported commands, and real subprocess execution. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Julie Yaunches <[email protected]> Signed-off-by: Apurv Kumaria <[email protected]> Co-authored-by: Apurv Kumaria <[email protected]>
Outcome
Managed workflow agents now run OpenShell sandbox commands without loading sandbox-user startup files. PR Review Advisor specialists no longer abort when the OpenShell 0.0.116 non-root sandbox user cannot read
/sandbox/.profile.Reason
The OpenShell 0.0.116 cutover exposed a login-shell startup failure in the shared managed-agent runtime. OpenShell already provides
sandbox exec --no-login-shellfor this case, but NemoClaw's shared helper did not pass it.Related issues
Relates to NVIDIA/OpenShell#2668 and NVIDIA/OpenShell#2852. No NemoClaw issue is required for this localized CI regression.
