переключиться на другую файловую систему в качестве корня дерева монтирования (switch to another filesystem as the root of the mount tree)

Имя (Name)

switch_root - switch to another filesystem as the root of the mount tree

Синопсис (Synopsis)

switch_root [-hV]

switch_root newroot init [arg...]

Описание (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.

Параметры (Options)

-h, --help
           Display help text and exit.


       -V, --version
           Display version information and exit.

Статус выхода (Exit)

switch_root returns 0 on success and 1 on failure.

Примечание (Note)

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
