## Summary - skip nonexistent `workspace-write` writable roots in the Linux bubblewrap mount builder instead of aborting sandbox startup - keep existing writable roots mounted normally so mixed Windows/WSL configs continue to work - add unit and Linux integration regression coverage for the missing-root case ## Context This addresses regression A from #14875. Regression B will be handled in a separate PR. The old bubblewrap integration added `ensure_mount_targets_exist` as a preflight guard because bubblewrap bind targets must exist, and failing early let Codex return a clearer error than a lower-level mount failure. That policy turned out to be too strict once bubblewrap became the default Linux sandbox: shared Windows/WSL or mixed-platform configs can legitimately contain a well-formed writable root that does not exist on the current machine. This PR keeps bubblewrap's existing-target requirement, but changes Codex to skip missing writable roots instead of treating them as fatal configuration errors.
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
