Well the details of what one wants to do in the initramfs matter a lot here.
Like, does the udev rule itself actually need to be machine specific?
A general pattern that also works is to have "machine specific" configuration embedded in generic images that dispatches on machine specific identifiers hardware MAC addresses are a classic option, but not the only one.

This is operating system specific, I think we should just link to https://docs.fedoraproject.org/en-US/bootc/initramfs/

Do we need to duplicate these instructions vs just referencing the booting-local-builds.md?

This is a fully generic instruction that I think makes more sense in the booting-local-builds.md
BTW, the real problem with this is correct change detection; if you don't have reproducible builds then you're going to be pointlessly rebooting your machine some days...
