+# switch_root
+
+> Use a different filesystem as the root of the mount tree.
+> Note: switch_root will fail to function if the new root is not the root of a mount. Use bind-mounting as a workaround.
+> See also: `chroot`, `mount`.
+> More information: <https://manned.org/switch_root.8>.
+
+- Move `/proc`, `/dev`, `/sys` and `/run` to the specified filesystem, use this filesystem as the new root and start the specified init process:
+
+`switch_root {{new_root}} {{/sbin/init}}`
+
+- Display help:
