Codex Desktop + WSL: Luna 6 hits mountinfo path is not absolute, Luna 5.6 does not

Reproducible difference I noticed today in Codex Desktop + WSL. With Luna 6 , apply_patch fails with: fs sandbox helper failed error building bubblewrap command: mountinfo path is not absolute I reproduced it both in my real repo and in a fresh repo under /tmp . Same environment: Luna 6 in Desktop → fails Luna 5.6 in Desktop → works standalone Codex CLI 0.156.1 → works This looks like a sandbox/tool-routing difference rather than a repo problem. Posting this as a reproducible bug report in case it helps narrow down the issue.
