Hi, Mr. Bagas, Sir! I am talking about a problem with the CONFIG_LOCALVERSION_AUTO=y feature. I thought of a way to make an exact account of which patches were applied in a build i.e. adding patch checksum to 6.3.0-rc4-00034-gfcd476ea6a88-dirty, for currently the command # rpm -ivh --oldpackage <kernelname>-<build-no>.rpm install the kernels kernel-6.3.0_rc4mt+20230330_00051_g8bb95a1662f8_dirty-24.x86_64.rpm kernel-6.3.0_rc4mt+20230330_00051_g8bb95a1662f8_dirty-25.x86_64.rpm kernel-6.3.0_rc4mt+20230330_00051_g8bb95a1662f8_dirty-26.x86_64.rpm all overlapping (apparently everything after '-' [minus] sign is discarded, so one has to reboot to another kernel, i.e. 6.1.15, remove the offending kernel, and then install the new one in the sequence of testing. The CONFIG_LOCALVERSION_AUTO=y rpm build script might add something that rpm command sees in the install process so the files do not overlap (as kernel names are being truncated at '-' sign). A smaller hash of the applied patches would suffice, considering the limit of 64 chars. Or using an underscore '_' instead of minus '-', so the rpm installer doesn't treat them as the same version of kernel. Is this a violation of the build process? It would be time and energy efficient, for changing the .config and CONFIG_LOCALVERSION causes much greater recompilation and touches more dependencies. Optionally, a /proc/<applied-patches-to-build> or something like that could be added to the running kernel, much like i.e. TuxCare has kcarectl --patch-info for live patches? Thank you very much for considering this problem report.
