I am aware of the differences. I just noticed your interest in smaller
footprint, and apart from the different languages used the main
difference between yaird and initramfs-tools is if probing is done at
ramdisk build time or at target boot time.

I believe boot time NIC probing is possible with much smaller footprint
than is required by udev. Currently what I do myself is simply to
force-load 21 popular NIC drivers without probing. My ramdisks is 1.5MB
(3.5MB uncompressed) compared to 4.4MB (10.2MB uncompressed) for
initramfs-based x86 ramdisks.


Good luck with your project :-)
