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 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. OPTIONS
-h, --help show help and exit -V, --version show version number and exit RETURN VALUE
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 SEE ALSO
