[Bug 244141] Re: Grub: Add detection of bootable disk partitions by UUID
Patch committed to lp:~ubuntu-core-dev/grub/ubuntu. I noticed that the changelog entry you provided included a rather extensive bit of explanation of this new feature: uuid command works in two ways, either by specifying the root device to boot from by the uuid number: uuid UUID-NUMBER or to list the uuid's on the supported filesystems on all bootable devices when the UUID-NUMBER is not listed, e.g.: uuid I think this belongs in some sort of documentation, not in the changelog. Could you provide a patch to docs/grub.info that documents the new uuid functionality, so that this information will be available in the grub-doc package? -- Grub: Add detection of bootable disk partitions by UUID https://bugs.launchpad.net/bugs/244141 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can anybody point me to the relevant patches - from my understanding Robert Millan has implemented UUIDs in grub, but without being able to examine the source I cannot easily compare and contrast the two implementations.

[Bug 244141] Re: Grub: Add detection of bootable disk partitions by UUID
Steve, From my understanding of the patches, they are to do with grub-update identifying the disk by examining /dev/disk/by-uuid. This is different to my set of patches which do UUID identification at boot time inside the boot loader (my code uses raw BIOS reads of the underlying filesystem and some uuid magic via the uuid library borrowed from udev). From what I can understand from the message in http://www.nabble.com /UUID-support-in-GRUB-td17586784.html the boot from uuid part is not yet implemented in grub-0.9x. It appears there is some experimental UUID support in grub2 that would needs to be back ported to 0.9x -- which could be as unpleasant as writing it from scratch.

I've reviewed Robert Millan's mail to debian-boot, and I see that he says: I'm in the process of enabling UUID support in GRUB. This basically means two different things: 1- GRUB should use UUIDs internally to identify the devices it needs to access (for example, which device contains your /boot), regardless of how BIOS assigns numbers. 2- update-grub should automatically detect the UUID of your root filesystem and tell Linux about it via root=UUID=xxx parameter. Latest grub2 in unstable (1.96+20080601-1) is already doing #1 (to some extent) and #2 (although #2 can be disabled). #1 I don't expect to see in grub legacy; but #2 is trivial to implement. My plan is to use grub2 as a testbed for this feature, and if no problem arises add it to grub legacy as well. So indeed, he doesn't have any intention of implementing UUID support directly in GRUB1. Thanks, I'll poke at your patches later today. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.

[Bug 244141] Re: Grub: Add detection of bootable disk partitions by UUID
Hi Colin, How does this patch relate to the UUID support that's being added to the Debian grub package? It would be great if we could sync up with Debian on this and be using the same code. ** Changed in: grub (Ubuntu) Target: intrepid-alpha-1 = intrepid-alpha-2 -- Grub: Add detection of bootable disk partitions by UUID https://bugs.launchpad.net/bugs/244141 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 244141] Re: Grub: Add detection of bootable disk partitions by UUID
Attached is a debdiff that supports grub boot for UUID for Intrepid. It supports booting by UUID for the following partition types: PartitionTested ext2Y ext3Y fat/vfatY jfsY reiserfs Y xfs Y ocfsN ddf_raid N hfs N luksN The tests were performed by creating several partitions on a 4Gb USB Mass Storage Device of the above types and copying /boot into each partition and then booting from the relevant partition. Partitions 1-4 and logical partitions 5+ were tested on USB and physical hard disks. A typical grub menu.lst using the uuid command is as follows: title uuid ext3 uuid98ab0550-7e12-4da7-ad6d-3d7dc9b32ab0 kernel /boot/vmlinuz-2.6.24-19-generic root=UUID=98ab0550-7e12-4da7-ad6d-3d7dc9b32ab0 ro quiet splash initrd /boot/initrd.img-2.6.24-19-generic title uuid vfat uuid4868-85B1 kernel /boot/vmlinuz-2.6.24-19-generic root=UUID=4868-85B1 ro quiet splash initrd /boot/initrd.img-2.6.24-19-generic One extra feature is just using the uuid command without specifying a UUID will cause grub to find and print out all know (and supported) UUID's that it can boot from, in the form: (hdX,Y)filesystemuuid e.g.: (hd0,0) ext3 98ab0550-7e12-4da7-ad6d-3d7dc9b32ab0 (hd1,0) vfat4868-85B1 (hd1,1) xfs 6f2ebb0f-f6d1-4e7b-9292-942c0c3d021b Note: The UUIDs must match those as reported by `ls /dev/disk/by-uuid` - some filesystem UUID's are derived from volume labels and the UUID matching is case sensitive. ** Attachment added: Intrepid Grub 0.97 UUID debdiff http://launchpadlibrarian.net/15685494/grub-0.97.uuid.debdiff ** Changed in: grub (Ubuntu) Importance: Undecided = Wishlist Target: None = intrepid-alpha-1 -- Grub: Add detection of bootable disk partitions by UUID https://bugs.launchpad.net/bugs/244141 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
