At least with the RH 7.3 installer you could unselect a whole lot of those unneeded services and they wouldn't even get installed. With the new 8.0 installer it's darn near impossible to leave that stuff out. You have to install all of it and then go back and remove the packages afterwards. Of course with all the RPM dependencies you only get to remove half of what you really want to get rid of.
But! Install Win2k server and you'll find the same is true so RedHat is getting closer andcloser to thier target goal.
