switch_root - switch to another filesystem as the root of the mount
switch_root newroot init [arg...]
switch_root moves already mounted /proc, /dev and /sys to newroot and
makes newroot the new root filesystem and starts init process.
WARNING: switch_root removes recursively all files and directories on
the current root filesystem.

switch_root returns 0 on success and 1 on failure.
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
mount(8) chroot(2) init(8) mkinitrd(8)
