SWITCH_ROOT(8) System Administration SWITCH_ROOT(8)
switch_root - switch to another filesystem as the root of the mount
tree
switch_root [-hV]
switch_root newroot init [arg...]
switch_root moves already mounted /proc, /dev, /sys and /run 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.
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
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
chroot(2), init(8), mkinitrd(8), mount(8)
