Hello, I've got a question about how is the rebuilding of external kernel modules invoked during a new kernel version installation? The reason I'm asking is because when I install a modified kernel the Nvidia GPU driver modules are not built and installed like they are for regular kernels. Example how it works with standard kernel: I have kernel-default-5.10.3, kernel-default-5.10.4 is released, I run zypper dup, during the kernel installation the Nvidia modules are rebuilt against the new kernel and installed. I can reboot into the new kernel and everything works. Example with my situation: I take the kernel source kernel-source-5.10.4 from the standard Tumbleweed repos, make a few changes, build the rpms (make rpm-pkg), install them with Zypper but it doesn't install the Nvidia modules, I have to do this manually or else the GUI wouldn't work. So what exactly triggers the module rebuild? What does the official kernel rpm has that my rpm built for the same source doesn't?
