The script responsible for updating the /boot/initrd.img symlink is called `linux-update-symlinks`. If a kernel is installed without that script being run, the symlink will not be updated.
The only place where `linux-update-symlinks` is run is inside each of our kernels, in `debian/templates/image.postinst.in`. This means that when our kernels are built as .deb packages, the appropriate machinery will be placed inside the .deb to thus update the /boot/initrd.img symlink. I checked the change history to `installkernel` and could not find any point in time in which it ran `linux-update-symlinks`. Furthermore, the help info inside `linux-update-symlinks` contains the following note: "This command is intended to be called from the postinst and postrm maintainer scripts of Linux kernel packages." It looks like `linux- update-symlinks` was only ever intended to be used in postinst/postrm hooks for .deb packages (and not called by `installkernel`). There are a few remedies to this problem I can see, but I'm not sure which is the correct solution: 1. Add a call to `linux-update-symlinks` into `installkernel` or 2. Add a script into /etc/kernel/postinst.d to run `linux-update-symlinks` or 3. Run `linux-update-symlinks` manually after installing a kernel directly via `installkernel` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877088 Title: [UBUNTU 20.04] installkernel script does not symlink /boot/initrd.img which is required with the default zipl.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1877088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
