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 and exit.

switch_root returns 1 on failure, it never returns on success.

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
