Hi Matt, There actually has been quite a lot of progress made here, though admittedly the state of documentation is somewhat confusing...
Here are some more resources to check out: The LinuxBoot book has more up-to-date examples: https://github.com/linuxboot/book/blob/master/7b.UEFI_Tool_Kit/README.md Fiano is a set of tools for manipulating UEFI firmware: https://github.com/linuxboot/fiano Go Forth and Modify with Fiano (2019 OCP Summit): https://www.youtube.com/watch?v=FrylZsqyi0c Slack channel (join the linuxboot channel): http://slack.u-root.com/ Mailing list: https://groups.google.com/forum/#!forum/linuxboot The naming has also gotten a bit confusing over the years. As I understand it, NERF is more of a general concept of reduced UEFI. Fiano is a toolset and LinuxBoot just implies replacing BDS and portions of DXE with Linux and an initramfs to load and execute the target OS kernel. HTH!
