-h, --helpDisplay help text and exit.
Print version and exit.
EXIT STATUS
switch_root returns 1 on failure, it never returns on success.NOTES
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
