I don't see that being informative for this problem.

Quite the opposite; this is a very useful suggestion. Imagine that
update-grub didn't give you something workable. You would (or should)
be glad of the opportunity to roll your own. I do it all the time with
removable devices.

In your case, if grub-install had given you a "root=" line in a stanza
it is possible you would not be booting the SD card. A 40_custom file
needn't have it in.


I'll add it to my TODO list.
I've never attempted to edit /etc/grub.d/40_custom file or its cousins.
I've just received some need documentation for something I'm doing for someone else.
Anyone have a few spare 100 hour days ;/
