parrot_namespace - run a command in a modified namespace.

parrot_cp [options] <command>

parrot_namespace detects whether it is already running under Parrot and either forks a new mount namespace in the existing Parrot session or simply executes parrot_run. For applications that only need to make mount-related changes, parrot_namespace is a drop-in replacement for parrot_run that automatically handles nested invocations.

 -M, --mount /foo=/bar
Mount (redirect) /foo to /bar (PARROT_MOUNT_STRING)
 -m, --ftab-file <path>
Use <file> as a mountlist (PARROT_MOUNT_FILE)
Path to ld.so to use.
 --parrot-path
Path to parrot_run (PARROT_PATH)
 -v, --version
Show version number
 -h, --help
Help: Show these options

On success, returns zero. On failure, returns non-zero.

To run Parrot under Parrot with a modified mount environment, use parrot_namespace

% parrot_namespace -M /tmp=/tmp/job01 sh
% parrot_mount --unmount /tmp    # not allowed

Now in the same shell, we can call parrot_namespace regardless of whether we're already running under Parrot or not.

% parrot_namespace -m mountfile foo
