switch_root
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, /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.
OPTIONS -h, --help
Display help text and exit.
-V, --version
Display version information 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
