In the latest pre-release 1.1.2.15 Yliaavanlampi I needed to do a couple of changes to get android stuff working from the sdcard.

First one in the mount-sd.custom.sh:
ACTION=$1

if [ "$ACTION" = "add" ]; then
mount /dev/mmcblk1p1 /mnt/sd
mount -o bind /mnt/sd/.home /home/nemo
mount -o bind /mnt/sd/.android /data/media
else
umount /data/media
umount /home/nemo
umount /mnt/sd
fi

this seems to be only one of possible ways.

Then /opt/alien/system/alien.sh as chem|st developed :
move word 'data' from this line (19 in the file) to the next for statement

for d in bin sbin lib usr var etc tmp home vendor data; do
if [ "" == "$(grep $ROOT/$d /proc/mounts)" ]; then
echo "mount $ROOT/$d"
mount --bind /$d $ROOT/$d
fi
done

for d in dev sys run data; do
if [ "" == "$(grep $ROOT/$d /proc/mounts)" ]; then
echo "mount $ROOT/$d"
mount --rbind /$d $ROOT/$d
fi
done
