I've built a few custom initramfs files, and while I haven't streamlined
it all into a script, I work dependencies out by running

     ldd <binary>

This gives a list af all the required lib files for any given binary.

You could probably automate this step with something like

     ldd <binary>|awk '/=>/ {print $3}'

As to the size: initrd files had a size constraint, but initramfs files
do not. Maybe this is what you heard?
