Hello Chris, or anyone else affected, Accepted grub2-signed into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/grub2-signed/1.66.8 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

Matching subscriptions: Ubuntu 16.04 Bugs https://bugs.launchpad.net/bugs/1640878 Title: grub2 cannot currently generate configuration without initrd Status in grub2 package in Ubuntu: Fix Released Status in grub2-signed package in Ubuntu: Fix Released Status in grub2 source package in Xenial: Fix Committed Bug description: As it currently stands grub2 cannot create grub.cfg menu entries that do not use an initrd image if one is present but the user does not desire to use it. Furthermore, root= entries only support UUID and LABEL, but neither is an option if booting the kernel without an initrd. Suggestion: Allow grub2 to create configuration files without an "initrd" line and passing PARTUUID as root= entry by adding configuration knobs. [SRU Justification] A lot of time is wasted across the many, many instances of Ubuntu loading initramfs when booting. It's a measurable savings of CPU time and electricity to skip loading an initramfs at boot if it's not required. [Test case] 1. cp /boot/grub/grub.cfg /tmp/grub.cfg 2. install the grub packages from -proposed. 3. cmp /boot/grub/grub.cfg /tmp/grub.cfg || echo 'fail' 4. as root, configure /etc/default/grub to mount the root disk directly and bypass the initramfs: echo GRUB_DISABLE_INITRD=true >> /etc/default/grub root=$(awk </etc/fstab '$2 == "/" { print $1 }') case $root in LABEL=*|UUID=*) dev="-l -t $root" ;; *) dev=$root ;; esac partuuid=$(blkid -s PARTUUID -o value $dev) if [ -z "$partuuid" ]; then echo "Error: cannot get partuuid for $root." else echo GRUB_FORCE_PARTUUID=$partuuid >> /etc/default/grub fi 5. If a partuuid has been found, run update-grub. Note that this will only work if your root device is a partition on a GPT-formatted disk. 6. Check that /boot/grub/grub.cfg now contains entries that don't specify an initramfs, and do include root=PARTUUID=* on the kernel commandline. [Regression potential] This upload introduces no behavior changes unless the user updates /etc/default/grub to configure the use of the new feature, so there should be no regressions here. The SRU test case verifies that /boot/grub/grub.cfg remains unchanged with the new version.
