rpm spec call uname -r

When I install my app, I would like to copy some files in /lib/modules/KERNEL_VERSION/extra.

The problem of course is that KERNEL_VERSION is not fixed.

I can find it by calling "uname -r", but how do I do this in a rpm spec file?

Also, if there's a better method, I'm opened to ideas.

This isn't a good idea because you should compile kernel modules on the client machine with a %triggerin so it survives a kernel upgrade.

The answer to this question will probably leave you with symbol mismatches when trying to load kernel modules compiled for a different kernel.

To place the kernel modules at compile time, do as Delan answered:

%files
/lib/modules/`uname -r`/extra/*.ko

To place the previously compiled kernel modules in the currently running kernel's path, you will have to do something tricky in the %post section:

%post
cp /lib/modules/known/location/*.ko /lib/modules/`uname -r`/extra/*.ko

%postun
rm /lib/modules/... # hopefully they have not upgraded their current kernel..

%files
/lib/modules/known/location/*.ko

Which will install kernel modules that probably can't be loaded on the running kernel. Usually source RPMs are the solution for this exact problem.

You could interpolate the result of uname -r into the directory (guessing here):

/lib/modules/`uname -r`/extra/
