First, I'm inexperienced with the mailing list and GRUB development processes. Let me know if I'm going about this correctly.
The Bedrock Linux project has been wrestling with a GRUB update issue. There is a Github issue[1] containing relevant info that I will summarize here. The current theory is that, due to Bedrock's use of bind mounts on the root directory, /proc/self/mountinfo may contain multiple entries with identical major:minor numbers. This (we think) is causing grub-mkrelpath to choose the wrong one, leading to an incorrect boot configuration. I intend to write a patch but want to gather whatever information I can before I take to programming.
