Curtin is collecting by-id links to disk to populate grub2 's debconf value:
grub-pc grub-pc/install_devices It's not clear to me (yet) if providing non persistent values (like /dev/sda) will work with /usr/lib/grub/grub-multi-install Even if it accepts non-by-id values; it's possible that on subsequent boots (with additional disks present) that /dev/sda might not point to the disk that has grub. So we can change this from an error by falling back on the path value, but it's just not safe. Disks need persistent attributes (like serial) for persistent links to work as expected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876258 Title: ubuntu 20.04 pxe installation fails with no such file or directory /dev/disk/by-id exception To manage notifications about this bug go to: https://bugs.launchpad.net/curtin/+bug/1876258/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
