[yocto] Yocto General purpose evaluation

[Timothy Froehlich]

Sounds like you should be using an embedded Linux, since only including the
minimum required software will help keep your image small and power usage
down. Removing audio, video and usb, including from your kernel config,
should drastically reduce your size.

You should consider the value of a read only FS, since I'd assume you'll
have random power loss due to solar being your primary power source.
Yocto/Buildroot will be much better with that.

For Yocto vs Buildroot, here's a good place to start for your research:
https://lwn.net/Articles/682540/. In my experience, Buildroot is easy,
simple, and great as long as you're building one thing. Yocto is much more
powerful and if you need more than what Buildroot can provide then you're
better off investing your time learning Yocto instead of learning how to
modify Buildroot, IMO.
