SWITCH_ROOT(8)                        System Administration                        SWITCH_ROOT(8)



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)
