switch_root - switch to another filesystem as the root of the mount tree
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
WARNING: switch_root removes recursively all files and
directories on the current root filesystem.
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:
- -h, --help
- Display help text and exit.
- -V, --version
- Display version information and exit.
