I use initrd for a somewhat... different reason to most. The kernel is statically compiled for the hardware, so It does not contain modules, initialisation scripts, etc. it contains the entire root fileystem of the unit which then runs entirely in RAM. One of my running boxes: dsx$ df -h Filesystem Size Used Avail Use% Mounted on /dev/ram0 136M 83M 54M 61% / and I really can, as root do: rm -rf / without any issues whatsoever. Just power cycle and it's back :) I could run root directly out of flash, but that's slower and even though flash devices are 'good' these days with automatic write wear levelling, and such-like, I still feel that if you don't need to write to it, then don't.
