       The switch_root command is part of the util-linux package which can be downloaded from Linux Kernel
       Archive <https://www.kernel.org/pub/linux/utils/util-linux/>.

switch_root moves already mounted /proc, /dev, /sys and /run to newroot and makes newroot the new root
       filesystem and starts init process.

switch_root returns 1 on failure, it never returns on success.

       switch_root - switch to another filesystem as the root of the mount tree

switch_root will fail to function if newroot is not the root of a mount. If you want to switch root into
       a directory that does not meet this requirement then you can first use a bind-mounting trick to turn any
       directory into a mount point:

           mount --bind $DIR $DIR

-h, --help
           Display help text and exit.

       -V, --version
           Display version and exit.
