I'm not 100% certain, but I believe that any required service restarts are
handled by post-install scripts. I don't recall any that control services
that don't restart them automatically.

If you are looking to avoid all restarts, "chkconfig --list | grep 5:on"
will tell you which services are started at boot time. Upgrades to those
packages will almost certainly restart their own services.

To be absolutely sure you might have to examine the .spec files and any
referenced post-install scripts in all .src.rpm packages. Unless you
suffer from OCD, doing this for all 1,000+ packages in a minimum
installation will be a massive PITA.
