Description Bill Mills 2014-05-09 21:19:25 UTC 
grub-efi creates a very minimal grub image that can boot from a disk
It does not have the modules needed to netboot.
It also has zero extra commands to help someone out when something goes wrong.

In [1] I add more modules to the composite grub image to allow more features.
This comes with only a very moderate increase in size.

(The standalone composite image in [1] is out of scope for this request. See Bug#6307 for coverage of that.)

This is really an hour or so to change and get working.
The other time is senario testing and socialization.

Newcomer or Kevin if he ever has less to do in his WR work.
Comment 3 Randy MacLeod 2023-10-24 14:24:44 UTC 
Bulk move from 4.99 or 0.00 to 5.99
Comment 4 Alan Perry 2023-11-16 06:36:10 UTC 
I have done a lot of work on networked and efi GRUB and could probably figure this out.

However, this bug does not include a list of modules to add and the link to the composite grub image mentioned in elsewhere in this bug does not seem to work now.
Comment 5 Randy MacLeod 2024-04-25 01:08:31 UTC 
Move to 5.99 since no one is actively working on this issue.
Comment 6 Alan Perry 2024-04-25 04:18:06 UTC 
I am willing to work on it if the list of modules was identified.
Comment 7 Randy MacLeod 2024-04-25 15:41:39 UTC 
Thanks Alan!

I can't help with the list of modules so let's see if Kexin can.
If not, pick a couple that you think are useful and testable I guess.
Comment 8 Kevin Hao 2024-04-26 11:06:16 UTC 
Sorry, I also don't have the list of modules.
Comment 9 Randy MacLeod 2024-04-26 13:23:57 UTC 
Thanks for the reply Kexin.

Bill, are you able to provide an initial list to Alan?
Comment 10 Randy MacLeod 2024-05-02 14:54:34 UTC 
Add Anuj, who may also be able to provide a list of modules to test.
Comment 11 Anuj Mittal 2024-05-03 01:55:30 UTC 
The original bug seems to have been filed for Minnow board/32 bit and is quite old so the original list or steps might not be helpful anyway.

May be we can look at the Ubuntu script: https://git.launchpad.net/~ubuntu-core-dev/grub/+git/ubuntu/tree/debian/build-efi-images#n203 and see what they enable for network boot and enable and test?
Comment 12 Randy MacLeod 2024-05-16 15:28:35 UTC 
Bill, see Anuj's comment.
Comment 13 Alan Perry 2024-05-16 23:20:20 UTC 
Can someone describe a list of scenarios that might go wrong where additional commands would help? I know what I needed when I was trying to resolve network boot problems but I don't want to limit this to what I found I needed.
Comment 14 Randy MacLeod 2025-02-20 16:17:48 UTC 
Bill, please retake if you have time to work in this.
