NAMEswitch_root - switch to another filesystem as the root of the mount tree.
DESCRIPTIONswitch_root moves already mounted /proc, /dev and /sys 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.
- -h, --help
- show help and exit
- -V, --version
show version number and exit
RETURN VALUEswitch_root returns 0 on success and 1 on failure.
NOTESswitch_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
