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
