Research direction
No source file or test is named in the issue. Start by tracing bubblewrap's command-line handling for a new --netns FD option and compare it with the existing host and newly-created namespace paths. Done means an already-open namespace file descriptor can be selected for network sandboxing, with coverage for the option's behavior and errors.
Written by the indexing model from the issue text.
Description
The use case is for sandboxing a network service. I already have set up network namespaces to use, however bubblewrap doesn't seem to provide the option to use an already-existing namespace; it's either the hosts or a new one. As it stands one must use other container software (or unshare manually) to accomplish this.
