        "content": "You *don\u2019t strictly need* `bubblewrap` installed to run Codex on Debian 13\u2014in many cases, Codex comes with a *vendored* (embedded) copy of `bwrap` that it can fall back to. But whether you can run in \u201cauto-pilot\u201d mode (minimal confirmations) with acceptable safety depends on how you configure sandboxing, approval policies, and your kernel support. Here\u2019s a breakdown of how it works, what you\u2019ll need, and how to get automatic-ish behavior with fewer prompts.\n\n---\n\n## How Codex\u2019s sandboxing works on Linux\n\nCodex uses a combination of the following for sandboxing on Linux:\n\n- **Landlock LSM** + **seccomp** (system call filtering) \u2014 the legacy/default path.  \n- **Bubblewrap (\u201cbwrap\u201d)** \u2014 container-like isolation, mount namespaces, etc. This is newer and more robust. Codex supports a *vendored* `bubblewrap` that\u2019s built in if your system one is missing or unsuitable. ([github.com](https://github.com/openai/codex/blob/main/codex-rs/linux-sandbox/README.md?utm_source=openai))\n\nWhen you start Codex, it looks for `bwrap` in your system\u2019s PATH (e.g. `/usr/bin/bwrap`). If it\u2019s absent (or too old), Codex will:\n\n- Use its embedded bubblewrap helper. ([github.com](https://github.com/openai/codex/blob/main/codex-rs/linux-sandbox/README.md?utm_source=openai))  \n- Warn you: \u201cCodex could not find system bubblewrap \u2026 using vendored bubblewrap.\u201d ([github.com](https://github.com/openai/codex/issues/15282?utm_source=openai))\n\nSo **you are covered** either way, but system `bwrap` gives you more consistent behavior and lets Codex use features like `--argv0`.\n\n---\n\n## Do you need bubblewrap for \u201cauto-pilot\u201d / minimal confirmations?\n\nNot *necessarily*, but installing and using bubblewrap makes things smoother, especially for fewer prompts. Here\u2019s why:\n\n1. **More robust sandboxing means fewer triggered denials**  \n   Bubblewrap better isolates filesystem, mount points, protected paths (e.g. `.git`, `.codex`) and handles namespace isolation. With a reliable sandbox, Codex knows more precisely what operations are unsafe and what are allowed, so there are fewer \u201cfalse alarm\u201d prompts. ([mintlify.com](https://www.mintlify.com/openai/codex/architecture/sandboxing?utm_source=openai))\n\n2. **System bubblewrap with newer versions offers better compatibility**  \n   Features like the `--argv0` flag are used in Codex\u2019s bubblewrap integration. If your system\u2019s bubblewrap is too old (pre-0.9.0) or lacks required capabilities, Codex falls back to its vendored version, which works\u2014but might be slightly less performant or flexible. ([reddit.com](https://www.reddit.com/r/u_Fuzzy_Independent241/comments/1s3ocyl/codex_cli_v0116_breaks_on_ubuntu_lts_debian_with/?utm_source=openai))\n\n3. **Certain \u201callow only inside workspace; ask outside\u201d behavior** tends to depend on having working bubblewrap + properly set policies. Some users report that without bubblewrap, Codex ends up prompting much more often\u2014even for small things. ([reddit.com](https://www.reddit.com/r/codex/comments/1sh4rwg/codex_cli_allow_inside_workspace_ask_outside_what/?utm_source=openai))\n\n---\n\n## Configs & settings to reduce confirmations\n\nIf you want Codex to auto-run as much as possible (with minimal interactive confirmations), you\u2019ll want to tweak a few config settings and understand how approval policies work.\n\nHere are the main knobs:\n\n| Setting | Effect | How to tune |\n|---|---|---|\n| **sandbox mode** (`sandbox_mode`) | Controls filesystem & network restrictions. Options: `read-only`, `workspace-write`, `danger-full-access`. The more access, the fewer restrictions. ([openai-codex.mintlify.app](https://openai-codex.mintlify.app/concepts/sandboxing?utm_source=openai)) | For less interaction, use `workspace-write`. Use `danger-full-access` only in trusted setups. |\n| **network access policy** | Whether network operations are allowed. If disabled, every network request will require approval. ([openai-codex.mintlify.app](https://openai-codex.mintlify.app/concepts/sandboxing?utm_source=openai)) | Set `network_access = \"enabled\"` in config when needed. |\n| **approval policy / rules** | Which commands need approval, for how long. You can make per-session trust or global rules. ([mintlify.com](https://www.mintlify.com/openai/codex/architecture/sandboxing?utm_source=openai)) | Add allowlist rules in `~/.codex/config.toml` under the `rules` section (\u201callow\u201d specific commands). |\n| **full-auto / approval mode** | Tells Codex to apply edits automatically and decide about shell commands (approve, prompt, etc.) by policy. ([developertoolkit.ai](https://developertoolkit.ai/en/codex/lessons/automation?utm_source=openai)) | You might set `approval_mode = \"auto-edit\"` or similar, though full-auto means more risk. Be careful. |\n| **kernel & system settings** | Some sandboxing (bubblewrap+user namespaces) depends on kernel version, `unprivileged_userns`, and AppArmor, etc. If user namespaces are disabled, bubblewrap may fail or be much more restrictive. ([github.com](https://github.com/openai/codex/blob/main/codex-rs/linux-sandbox/README.md?utm_source=openai)) | On Debian, ensure `kernel.unprivileged_userns_clone=1` (or `0` must be set to allow?) and that bubblewrap is permitted to create namespaces. |\n\n---\n\n## Debian 13 specifics: what to check / do\n\nSince you\u2019re on Debian 13, here are some Darwin/Bubblewrap-related gotchas and what to check:\n\n- **Check system bubblewrap version**: Run `bwrap --version`. If it\u2019s older than ~0.9.0, you\u2019ll hit issues with `--argv0` support. If too old, either upgrade or rely on vendored bubblewrap.  \n- **User namespaces / AppArmor**: Debian may have mechanisms that prevent non-root users from creating namespaces. If that is blocked, bubblewrap might fail or enforce restrictive fallback behavior. You may need to enable unprivileged user namespace or adjust AppArmor profiles. Some users fixed overly chatty approvals by enabling `unprivileged_userns` or relaxing AppArmor. ([reddit.com](https://www.reddit.com/r/codex/comments/1sh4rwg/codex_cli_allow_inside_workspace_ask_outside_what/?utm_source=openai))  \n- **Debian\u2019s kernel version**: Landlock requires kernel 5.13+, with full support often in 5.19+. Debian 13 likely has an adequate version, but verify. Otherwise sandboxing may degrade. ([openai-codex.mintlify.app](https://openai-codex.mintlify.app/concepts/sandboxing?utm_source=openai))  \n\n---\n\n## So\u2014what\u2019s the recommendation?\n\nHere\u2019s what I suggest to get as close to \u201cauto-pilot\u201d as reasonably safe:\n\n1. Install `bubblewrap` from Debian\u2019s repo. This avoids odd fallback behavior.  \n   ```bash\n   sudo apt update\n   sudo apt install bubblewrap\n   ```\n\n2. Ensure `user namespaces` are enabled. If not, modify sysctl/AppArmor or kernel settings so that Codex can use bubblewrap properly.\n\n3. Set your Codex config to something like:\n\n   ```toml\n   [sandbox_policy]\n   mode = \"workspace-write\"\n   network_access = \"enabled\"\n\n   [rules]\n   # allow certain safe commands without asking\n   [[rules]]\n   match = \"npm audit\"\n   action = \"allow\"\n\n   [[rules]]\n   match = \"git status\"\n   action = \"allow\"\n   ```\n\n4. Use an approval mode / full-auto settings **only after** manually auditing a few runs, especially automations or background tasks. Turn on something like `auto-edit` or `full-auto` *with restrictions*.  \n\n5. For any automation / scheduled Codex tasks, make sure they run with your configured sandbox, not full access, so unintended changes require explicit permission. This will give you the freshest behavior once policies are in place. ([developertoolkit.ai](https://developertoolkit.ai/en/codex/lessons/automation?utm_source=openai))\n\n---\n\n## Bottom line\n\n- You *do not* need to have system `bubblewrap` installed; Codex will work (using its embedded `bwrap` or falling back to Landlock) on Debian 13.  \n- But installing `bubblewrap` + configuring sandbox & approval policies lets you reduce prompts and get \u201cautomatic\u201d behavior for many tasks\u2014without sacrificing security.  \n- Be cautious about using \u201cdanger-full-access\u201d or fully auto-approving changes, especially for commands outside your workspace.\n\nIf you want, I can help you generate a sample `~/.codex/config.toml` tailored to Debian 13 with minimal confirmations. Do you want me to lay that out?"
