no jail {id}

Error message

no jail {id}

What it means

A cwd-jail registry operation (rename here) looked up a jail id that does not exist in the in-memory registry. It is a NotFound io::Error sentinel from the get() precondition — the faulting input is the caller-supplied jail id string, which is stale, typo'd, or refers to a jail deleted from another process/registry instance.

Solutions

1. List jails from the registry to confirm which ids exist and re-issue with a valid id
2. If the jail was expected, check whether another session/process removed it or the registry index failed to load
3. Create the jail again if it was legitimately deleted but still needed
