I tend to use a reasonably standard image, usually the one that will evolve into the product, and once the network (usb, ethernet or wifi) is up, use "opkg install" to grab whatever else I need from my build machine on demand.

for a current project (and subsequent projects), i want to define a

precious little unnecessary userspace crud that has no value in that
context. (at the moment, the target is aarch64 but, naturally, the
ideal image would be maximally applicable no matter the target.)
i'm thinking of recipes that allow probing/configuration of memory
and busses and that sort of thing. off the top of my head:
* phytool (or other MDIO probe/debug tools)
the list can go on and on, and i just ran across this which i had
never seen before:
suggestions? i suspect numerous folks on this list have already done
something like this.
