FWIW, I added the /etc/fstab entry provide (for /dev/loop2) but I
still get this at the end (from build/tmp-angstrom_2010_x-eglibc/work/beaglebone-angstrom-linux-gnueabi/cloud9-image-1.0-r0/temp/log.do_rootfs

[...]
./media/mmc1/
./media/union/
./media/realroot/
loop: can't delete device /dev/loop1: Permission denied
loop: can't delete device /dev/loop2: Permission denied
loop: can't delete device /dev/loop3: Permission denied
/dev/loop1: Permission denied

Are you familiar with makebootfat?
