openSUSE kernels use CONFIG_LOCALVERSION instead of EXTRAVERSION

[brenns10]

Interestingly, the openSUSE kernels show up only with the x.y.z version number, and no extra release information.

The reason for this is that kconfigs fetches the version from the top of the kernel config file, for example:

#
# Automatically generated file; DO NOT EDIT.
# Linux/x86 6.12.0-105.51.5.el10uek.x86_64 Kernel Configuration

But for openSUSE:

#
# Automatically generated file; DO NOT EDIT.
# Linux/x86 6.17.7 Kernel Configuration

The RPM name for this kernel is kernel-default-6.17.7-1.1.x86_64.rpm, and I'm guessing that if you run uname -r you would get 6.17.7-1.1.x86_64 (though I am testing it out in a bit). It turns out the extra comes from the CONFIG_LOCALVERSION. I haven't seen any other kernel that does it this way. I could append the CONFIG_LOCALVERSION to the version from the top of the config file, which seems like it would work.

The only other kernels with a LOCALVERSION set are a few android kernels.

Hm:

$ uname -r
6.17.7-1-default
