Ok, so the partition is already mounted for the environment to /boot, so you get -EBUSY when trying to automount it somewhere else. The question arises why you want to access it via automount when you already mounted it for your environment. Anyway, maybe we can do better by just mounting the partition to its standard location the autmount would use anyway and just create a symlink from /boot to /mnt/mmc1.0. I just sent a patch for this, you could give it a try.
