100MB is really not that large for an initrd.
Consider the deployment of stateless nodes - something that
virtualization allows the rapid deployment of. 1 kernel, 1 initrd with
the various binaries to be run. Create nodes as needed by launching a
shell command - be it for more capacity, isolation, etc. Why require an
iso or disk wrapper for a binary blob that is all to be run out of
memory? The -append argument allows boot parameters to be specified at
launch. That is a very powerful and simple design option.
