plugging the old drive on the new mobo just works. There is no prep in

network controllers have nothing in common.
I'm not sure it's a good idea to optimize away such robustness.
To be honest I found myself doing this sort of swap a lot more in the
past when hardware was less reliable and I was more inclined to cobble
systems together with parts found lying around the place: in those days
the initrd was host-specific by default and I didn't find it a headache
- much less of a headache than loading something with all the modules
included on each boot.
Maybe on modern hosts that's less of a concern for many users though
(although I do see noticeable pauses during initramfs loading on quite a
few systems with default configs).
I've been switching this setting on my boxes since dracut first came in
so I can carry on with or without the feature and it makes little
difference.
