Description

See https://github.com/coreos/bootupd/pull/228 and https://github.com/coreos/bootupd/pull/203

Basically to test upgrades, we're downgrading to an older grub build which is broken. We're just testing that the synthetic process of changing files actually works, but we're not currently testing rebooting into it.

Instead, we should download the working RPM and tweak it by:

  • adding files (safe)
  • Figuring out a way to mutate e.g. shim or grub binaries in a benign way that doesn't affect functionalty (this will (hopefully) not work with Secure Boot though), but at least we can reboot in non-SB UEFI

Research direction

Start by reading PRs #228 and #203, then inspect the current CI flow that downgrades to an older GRUB RPM and exercises the synthetic file-changing process. Done means CI downloads a working RPM, safely adds files, and explores benign binary mutation so upgrades can test rebooting on non-Secure-Boot UEFI.
