Well, since it's the root fs, I can't mount it twice, but I already have
the btrfs root volume set up in fstab to be mounted in /mnt/btrfs, so it
looks like this:
daniel at lnxsrv:~$ sudo mount /mnt/btrfs
daniel at lnxsrv:~$ ls /mnt/btrfs/@/boot/
abi-3.0.0-17-generic config-3.2.0-24-generic initrd.img-3.2.0 memtest86+_multiboot.bin vmcoreinfo-3.0.0-17-generic
abi-3.2.0-24-generic grub initrd.img-3.2.0-24-generic System.map-3.0.0-17-generic vmlinuz-3.0.0-17-generic
config-3.0.0-17-generic initrd.img-3.0.0-17-generic memtest86+.bin System.map-3.2.0-24-generic vmlinuz-3.2.0-24-generic
FYI, in fstab:
UUID=aa16e554-8ba2-4537-8bc6-a2c37f160369 /mnt/btrfs btrfs defaults,noatime,noauto,ssd,subvolid=0 0 0

Title:
Most recent grub update uses root=/dev/sdX for boot image, may fail to
boot
Status in “grub2” package in Ubuntu:
Incomplete
Bug description:
Hello :)
The recent update (today) of grub,
grub-pc:amd64 (1.99-21ubuntu3, 1.99-21ubuntu3.1)
grub-pc-bin:amd64 (1.99-21ubuntu3, 1.99-21ubuntu3.1)
grub-common:amd64 (1.99-21ubuntu3, 1.99-21ubuntu3.1)
killed my grub, apart from also looking strange (used to be gray background, and a nice logo splash when booting, now black background and just low-res text when booting).
The BOOT_IMAGE command defined root as - in my case - /dev/sdq2, while
at boot it would be /dev/sdb2. Also, this might not stay the same
regardless, and as I understand it, this should point to either a
partition UUID or perhaps /dev/disk/by-id/something-or-other?
In any event, as it stands, all boot options ends with busybox and an
initramfs prompt. Editing the grub command and fixing the root= to the
right path before booting will send me normally into Kubuntu where I
can (hopefully) fix the problem manually.
Cheerio :)
Daniel
