- * Can run in 3 modes:
- *
- * nstool hold <path>
- * Designed to be run inside a namespace, opens a Unix domain
- * control socket at <path> and waits until instructed to stop
- * with "nstool stop <path>"
- * nstool pid <path>
- * Prints the PID of the nstool hold process with control socket
- * <path>. This is given in the PID namespace where nstool pid
- * is executed, not the one where nstool hold is running
- * nstool stop <path>
- * Instruct the nstool hold with control socket at <path> to
- * exit.
