[OpenAFS-devel] Do depmod for correct kernel version on kernel module post-install

[Derek Atkins]

I'm sure it works fine for 2.6 builds..  It's 2.4 that worries me.

%{kxmoddir} is sometimes modified..  (see the files section).
Perhaps I need to duplicate the files section into the depmod.
I suspect that would do the right thing in all cases.
