After many years of doing embedded Linux stuff I still don't 
understand why people are so fond of initrd.

For temporary stuff - tempfs is much better and flexible. For r/o 
stuff - just make separate MTD partition (cramfs, squashfs) and mount 
it directly as root. Both options will waste significantly less 
memory.
