NAME

       parrot_namespace - run a command in a modified namespace.

SYNOPSIS

       parrot_cp [options] <command>

DESCRIPTION

       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.

OPTIONS

        -M, --mount /foo=/bar
              Mount (redirect) /foo to /bar (PARROT_MOUNT_STRING)

        -m, --ftab-file <path>
              Use <file> as a mountlist (PARROT_MOUNT_FILE)

       -l, --ld-path=<path>
              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

EXIT STATUS

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

EXAMPLES

       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
