NAME

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

SYNOPSIS

       switch_root [-hV]

       switch_root newroot init [arg...]

DESCRIPTION

       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.

OPTIONS

       -h, --help
              show help and exit

       -V, --version
              show version number and exit

RETURN VALUE

       switch_root returns 0 on success and 1 on failure.

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

SEE ALSO

       mount(8) chroot(2) init(8) mkinitrd(8)
