Well, the first writable branch would be IN the initramfs to start with. Heres how it generally plays out with all the previous aufs versions in pseudocode:
#INSIDE initramfs: mkdir "union" mkdir "rewriteable" mount -t tmpfs -o size=1024M tmpfs "rewriteable" mount -t aufs -o nowarn_perm,...,br:rewriteable=rw aufs union for each external squashfs filesystem: mount -o loop filesystem filesystem_dir <add branch to aufs> chroot "union" switch_root #finish Note that all the things happen INSIDE the initramfs, and the first writeable branch is of tmpfs and the union is of type initramfs. So now with the new versions, it fails on "mount -t aufs -o nowarn_perm,...,br:rewriteable=rw aufs union", which I assume is the newest feature about nfs...sure you can make it work in tmpfs (just like every previous version) no?
