Is it a directory on / which is on Btrfs? If so, I know what the problem is. Grubby doesn't understand btrfs subvolumes still, which is a bit baffling because GRUB2 has understood them for a long time by just treating them as directories. Anyway, what's really mounted at / isn't your Btrfs volume, but rather a subvolume named root. Same for home, the home subvolume is mounted at /home. So if you were to mount your Btrfs volume (without -o subvol) you'd see two directories: root and home which behave like directories but they are really subvolumes. And grubby can't figure out that the actual path to finding the kernel is: /root/boot/, and finding grub stuff is: /root/boot/grub2 > I don't know how to debug that further or where are this templates > located? They are tests baked directly into grubby, and the message is saying that the test has failed so grub.cfg isn't being modified. > > And is this normal? Yes, because grubby doesn't grok Btrfs subvolumes, and the maintainer doesn't really see the point for /boot on Btrfs anyway. There are patches to fix this that appear to work but they haven't been merged yet. So right now if you want to have /boot on a Btrfs subvolume, then you do one of two things: always run grub2-mkconfig after each kernel update, or use an out of tree grubby that understands Btrfs subvols. http://www.redhat.com/archives/anaconda-devel-list/2014-June/msg00023.html Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
