@Mathieu, thanks for your work on this. Regarding the test cases, I think that the second case needs an additional step:
-- initramfs update -- 1) install Ubuntu, using ZFS as a rootfs. 2) change 'MODULES=most' to 'MODULES=dep' in /etc/initramfs-tools/initramfs.conf 3) run "sudo update-initramfs -u" Without the second step, 'update-initramfs -u' will succeed even without the fix because 'MODULES=most' will probably result in the zfs module and necessary drivers being included anyway. I ran through this updated version of the test case on 18.04 with the package from the -proposed repository, and verified that the new version of the package fixed the issue. As far as the first test case, I'm not sure I have a simple way to test that one. I have a straightforward way of building with zfs on root for 18.04 and newer, but not 16.04. However, looking at the original bug report, it looks like the issue was building the initramfs for the kdump kernel, not the main kernel. I suspect that test case would need to include installing kdump-tools. This is for the same reason that test case #1 needs to be modified: by default, the initramfs for the main kernel is built with MODULES=most, whereas the kdump kernel by default is built with MODULES=dep, and this bug only affects making an initramfs with MODULES=dep. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661629 Title: upgrade of kernel fails with mkinitramfs: failed to determine device for / To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1661629/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
