.deb package uses very different maintainer scripts / codepath, and is not the same operation as "sudo make install". I personally always build my kernels as debs, and install debs, rather than doing "sudo make install". But I am a distribution developer, and I care for .debs to work right. Kernel developers, I guess, are inverse, and care for "upstream" $ sudo make install to work. > > Not with the /etc/kernel-img.conf[0] and not without it either. > As before the /boot/vmlinuz link is always updated. > That is slightly concerning, as to how $ sudo make install, ever worked before..... Or what has changed since. Normally, $ sudo make install, should lookup if /sbin/installkernel is available, and call that to "do what it has to do, on a given distribution", and that script is shipped by the debianutils package which is required and must be installed always. And it hasn't been touched in ages. I wonder which arguments are passed to /sbin/installkernel by $ sudo make install. And whether the 4th argument is passed, and if it is empty, /, or /boot. It should be either empty, or /boot. -- Regards, Dimitri. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-base in 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 Status in Ubuntu on IBM z Systems: Triaged Status in debianutils package in Ubuntu: New Status in linux-base package in Ubuntu: New Bug description: When testing development kernels I usually rely on the installkernel script either through the "make install" target of the Kernel source or manually. This used to work great on Ubuntu on Z. On Ubuntu 20.04 (freshly installed up to date) this fails however because /boot/initrd.img is not updated (/boot/vmlinuz is) and thus zipl installs the wrong kernel/initrd combination rendering the system unbootable.
