does /etc/sysctl.d/ really obeyed and does really override /etc/sysctl.conf

It would be better to keep upstream kernel defaults, especially so that
someone building their own kernel wouldn't get different settings
without any obvious documentation.  I don't see a problem with Fedora
deciding on different defaults, but it is much more obvious to a system
admin if they're in a config file rather than the kernel source.

The default file should probably then not be marked as a config file in
the RPM (and should be commented as such).  There should still be an
/etc/sysctl.conf with just comments pointing to the various places.

I don't speak for anybody but myself - that's enough trouble.
