[Bug 2060168] Re: Prebuilt signed grub images should include f2fs and exfat modules

[Adam Vodopjan]

> any practical utility

Recent ubuntu desktop iso images are way over 4Gb in size, which is the
max file size for fat32. Fat32 for long time was the obvious choice to
keep iso images on.

Exfat is of interest for those who still need compatibility with
w/ndows, like it was with fat32.

F2fs is of interest for those who want to use their flash storage with
the flash tailored fs.

BTW Debian's signed grub image includes f2fs module for 4 years
already[1]

Title:
  Prebuilt signed grub images should include f2fs and exfat modules

Status in grub2-unsigned package in Ubuntu:
  Won't Fix

Bug description:
  I guess this is the correct source package to send a feature request
  for debian/build-efi-images script.

  Here is what I ask for:

  --- build-efi-images
  +++ build-efi-images.new

  Motivation: it is pretty easy to make recent ubuntu iso images loopback-boot from f2fs and exfat partitions, but it would not work with secureboot because the signed grub images from grub-efi-amd64-signed do not contain the modules.

  There are already bug reports for casper to make it boot from f2fs[1]
  and exfat[2]
