Thu 26 Apr 2012 01:06:54 AM UTC, comment #11: I agree sometimes it is very useful to have UUID and search for them, but ...when the partitions or disks are on the same machine, only. Having the same UUID on different PC's should be no issue for GRUB.

Wed 01 Feb 2012 06:33:36 PM UTC, comment #10: Ok. I see disk-IDs are not reliable in some situations. I just happen to work differently with grub-legacy. I just started using grub2, so I am still learning new ways I guess.

Wed 01 Feb 2012 06:09:23 PM UTC, comment #9: I think you didn't understand what I was saying: GRUB uses BIOS to access disks by default. And BIOS disk driver (known as int 13h) has no function to get the ID.

Wed 01 Feb 2012 05:49:58 PM UTC, comment #8: Yes, I believe in my case the disk id is taken from the disk, not the BIOS. I never checked that, really.

Wed 01 Feb 2012 05:39:28 PM UTC, comment #7: Actually supposing that you're on BIOS, there is simply no way to ask the device id from BIOS.

Wed 01 Feb 2012 05:31:32 PM UTC, comment #6: Ok I understand the concern. It seems in my specific situation it would work fine but not as default when looking into all configurations.

Wed 01 Feb 2012 03:38:37 PM UTC, comment #5: Looking into specs I discovered that this info is unavailable through BIOS. So while having sth like this is possible in platforms that support it or if you use direct disk modules, it's not viable as any kind of default. |

Sat 28 Jan 2012 02:54:40 PM UTC, comment #4: Duplicate UUIDs is a problem indeed. I wasn't sure the commands you listed where actually assigning new UUIDs without reformatting, that was the part I was missing. I will keep them in note for when I need them.

Sat 28 Jan 2012 02:46:49 PM UTC, comment #3: The part "as available through BIOS" wasn't gratuituous. Many BIOSes give garbage instead of ID.

Sat 28 Jan 2012 01:12:58 PM UTC, comment #1: Having same UUID for 2 different filesystems is recognised as an error and not running FS-specific tool to change UUID after clonning is a mistake. The disk IDs available through BIOS are unreliable. Having such extension is possible as long as it's not increasing the size of critical modules but it's minor.

If you do dd if=/dev/sda of=/dev/sdb bs=1M and then use sdb on another computer then there is no reason it wouldn't work. Also your question is unrelated to original wishlist item. So, it's not a right place to discuss it. Use appropriate mailing list.
