## 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
           Print version and exit.

## EXIT STATUS
       **switch_root **returns 1 on failure, it never returns on success.

## 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
