Ok, good.

So, do I understand it correctly that unionctl --add is the problem?
Then can't I just change the startGoboLinux script to mount all
squashfs's in one go?
mount -t unionfs -o dirs=/Mount/SquashFS/Foo=ro:/Mount/SquashFS/Bar=ro:...

If I'm going to recompile the kernel, is the new unionfs patches
included in the recipe so I can revert them and replace them with the
unionfs patches from some old gobokernel tarball?
