Boot from ISO - exFAT support missing

[Adrian Feliks]

Please add support for booting the ISO image via grub2 (loopback) in initrd.
For larger images and a USB sticks, FAT32 is no longer sufficient.
Most popular distributions already have support for exFAT in initrd (they can find and mount ISO on this filesystem).

Exfat support is not a question of ubuntu-cdimage, but of the kernel.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1906067

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

In grub2, the statement "insmod exfat" works fine for me.
The problem comes from the fact that exfat module is NOT included by default in INITRAMFS file created by mkinitramfs program ( remember that the file named initrd is in fact an initramfs file ). This may considered as a bug by omission.
Have a look at bug number 2038694.

I have already submitted a patch, waiting for approval:

[Steve Langasek (vorlon)]

You've filed a bug in debian against software which is not used in Ubuntu.

I don't know how Live ISO images are generated in Ubuntu. I thought it was the same as in Debian.
