Well I got it working.
Here is what I do in initrd.
1. Create directories
/sysroot/tmpfs
/sysroot/union
/sysroot/cramfs
2. Mount my goods
mount -t tmpfs none /sysroot/tmpfs
mount -t cramfs /dev/root /sysroot/cramfs
mount -t unionfs -o dirs=/sysroot/tmpfs=rw:/sysroot/cramfs=ro
none /sysroot/union
3. pivot root
pivot_root /sysroot/union /sysroot/union/initrd
4. exit linuxrc
Works great. I can create files in tmp, etc.
I only have 2 problems.
1. When I compile the 1.0.4 unionfs module the result is a 3M file :(
2. After I do all this my memory usage is around 24m. Without doing
this it is only 5m.
I tried to strip the unionfs.o module but the result was a driver that
would load but not work.
