The Exherbo brouhaha
Don’t fault yourself as clueless just because you haven’t heard about the Exherbo yet. The distro-to-be seems to have gotten some attention for making it clear that your help is not needed, thank you very much.
There are plenty of opinions on the viability and attractiveness of a not-yet-published distro manned by a staff that is outright uninterested in drawing users, and most of them can be summarized here and here. (I only point to those threads because I’m most familiar with those forums, and most of those users.)
But I feel the need to be honest. About six or eight months ago I was seriously considering doing the same thing with a rearranged version of Ubuntu, mostly for my own edification, but also because I got tired of pruning and tweaking the default system to my liking. The obvious solution was to cook up something of my own invention with the packages and tweaks I like, preset and preinstalled. That way I could save time on testing and probing, since the majority of the performance settings I like would be in place already.
