Yes, I know busybox is in feature freeze. If this two-liner is too much that's fine, but it's handy. This patch allows busybox mount to support "-o move" just like it supports "-o bind", which is the equivalent of util-linux "mount --move". Usage is: mount -o move /mnt/point/1 /mnt/point/2 where /mnt/point/1 is an already mounted filesystem; it will be moved to /mnt/point/2.
