Add support for overlayfs
Created by: philmmanjaro
Since linux318 overlayfs is supported within Manjaro Linux. Currently we are using aufs within buildiso for all kernels. It would be also good to support another filesystem for our install medias. Here is a small example for how to use overlayfs:
mkdir -p /tmp/{lower,merged,upper,work}
sudo mount -t overlay overlay -o lowerdir=/tmp/lower,upperdir=/tmp/upper,workdir=/tmp/work /tmp/merged
