== 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.
|
|
|
|
== EXIT STATUS
|
|
|
|
*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
|
|
....
