Subject: cdrom: Keep the EFI image on the ISO9660 file system as well
X-Git-Tag: v2.21-core124~77^2~47
X-Git-Url: http://git.ipfire.org/?p=ipfire-2.x.git;a=commitdiff_plain;h=6b44fee76f2f086b8ac5378e1fdcf1fc000b70e6;ds=sidebyside

cdrom: Keep the EFI image on the ISO9660 file system as well

This allows systems to boot the EFI bootloader from the CDROM
file system instead of using the FAT filesystem which is for USB keys.
