I'd like to upgrade to GRUB 2.02 for trusty; it's currently in beta.
This represents a year and a half of upstream development, and contains
many new features. I've attached the relevant section of the NEWS file.
Obviously I want to be very careful with substantial upgrades to the
default boot loader. So, I've put this in trusty-proposed, and filed
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1269992 to ensure
that it doesn't reach trusty proper until it's had a reasonable amount
of manual testing. If you are already using trusty and have some time
to try this out, it would be very helpful to me. I suggest that you
only attempt this if you're comfortable driving apt-get directly and
recovering from errors at that level, and if you're willing to spend
time working with me on narrowing down any problems that arise.
Please ensure that you have rescue media to hand before starting
testing. The simplest way to upgrade is to enable trusty-proposed,
upgrade ONLY packages whose names start with "grub" (e.g. use "apt-get
dist-upgrade" to show the full list, say no to the upgrade, and then
pass all the relevant package names to "apt-get install"), and then
(very important!) disable trusty-proposed again. Provided that there
were no errors in this process, you should be safe to reboot. If there
were errors, you should be able to downgrade back to 2.00-22 (or
1.27+2.00-22 in the case of grub-efi-amd64-signed).
Please report your experiences (positive and negative) with this upgrade
in https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1269992. I'm
particularly interested in systems that are complex in any way: UEFI
Secure Boot, non-trivial disk setups, manual configuration, that kind of
thing. If any of the problems you see are also ones you saw with
earlier versions of GRUB, please identify those clearly, as I want to
prioritise handling regressions over anything else. I've assigned
myself to that bug to ensure that messages to it are filtered directly
into my inbox.
Thanks in advance,
