It's impractical to make these choices for all users. The kernel does an okayish job at choosing sane defaults. At a quick glance, some of those options are outright harmful (randomize_va_space is and should be '2' by default.) or outdated. Need to fiddle with tunables? Read the docs, test around - find out what works best for you.

ktide: i guess you're right... bu maybe we can at least supply some of those setting commented out with some brief description, so users will know about the interesting tunables. i think that archlinux have tradition of simple, well documented and easy-to-understand configuration files... (while still being vanilla)
