NAME
switch_root - switch to another filesystem as the root of the mount treeSYNOPSIS
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 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
