[Bug 377613] Re: jaunty install: formatting root partition changes uuid
Reformatting means a new UUID. Performing a new install includes installing grub, and generating a new config that will reference the new uuid. ** Changed in: ubiquity (Ubuntu) Status: Confirmed = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/377613 Title: jaunty install: formatting root partition changes uuid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/377613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 377613] Re: jaunty install: formatting root partition changes uuid
Although the OR did not respond to requests, I am confirming this report. Perhaps we can find a way to revert the UUID if the install fails. ** Changed in: ubiquity (Ubuntu) Status: Incomplete = Confirmed ** Changed in: ubiquity (Ubuntu) Importance: Undecided = Wishlist -- jaunty install: formatting root partition changes uuid https://bugs.launchpad.net/bugs/377613 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

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. If you could test the current Ubuntu development version, this would help us a lot. If you can test it, and it is still an issue, we would appreciate if you could upload updated logs by running apport-collect 377613, and any other logs that are relevant for this particular issue. ** Changed in: ubiquity (Ubuntu) Status: New = Incomplete -- jaunty install: formatting root partition changes uuid https://bugs.launchpad.net/bugs/377613 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 377613] Re: jaunty install: formatting root partition changes uuid
UUID is an UNIQUE identifier by definition, don't you think so? Hence, if you re-format partition it MUST change or UUID will make no sense. That's how it works - by design. Reformatting created DIFFERENT, new unique filesystem. Hence, UUID should get changed as well. But I have to admit that menu.lst probably should be re-generated with new UUID by installer in such cases and this still could be a bug if installer does not generated boot strings correctly. -- jaunty install: formatting root partition changes uuid https://bugs.launchpad.net/bugs/377613 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 377613] Re: jaunty install: formatting root partition changes uuid
I understand what you're saying (can't honestly say I understand UUIDs or what they're for though...) In my case, regenerating menu.lst wouldn't have made any difference, because having a failed installation meant that I had to restore it from my dumps, where the installer couldn't (and shouldn't) have touched it. So really the problem is the use of UUIDs in menu.lst. If that had been pointing at /dev/sda1 or hd(0,0) then restoring after a failed installation wouldn't be a problem. -- jaunty install: formatting root partition changes uuid https://bugs.launchpad.net/bugs/377613 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 377613] Re: jaunty install: formatting root partition changes uuid
Having now read up a bit on UUIDs, it seems to me that if an existing partition is being reformatted, it SHOULD retain the existing UUID. Anything referring to that particular partition by UUID will then still safely be able to find it if necessary. Although at one level a reformatted filesystem might be thought of as new and thus needing a new UUID, at the physical level, it's still the same part of the same disc, so is still the same filesystem, albeit wiped clean. It makes sense to allocate a new UUID for a newly-created filesystem, but to prevent difficulties after failed installs, pre-existing filesystems ought to retain their original UUID. I note from the man page that tune2fs can be used to set a chosen UUID for a filesystem, so there's no technical reason why this couldn't be done. And then someone in a disastrous situation such as mine could get working again with fewer problems. -- jaunty install: formatting root partition changes uuid https://bugs.launchpad.net/bugs/377613 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
