Basically, I have a very simple policy in my kernel life: - I don't touch distribution settings. I update the kernel, and NOTHING else. (Ok, I lie. I do my own git version too, but I'm really unhappy when I feel like I need to maintain anything else) And I have that policy because quite frankly, if I start tuning distro settings, I'll (a) forget about them and not do it on my next machine and (b) do some magic that _I_ may know how to do but nobody else does, so now what I'm doing is no longer relevant for anybody else (c) I'm no longer helping anybody else. So I have a few bits and pieces that I develop (mainly the kernel but also git etc), and I don't make site-specific changes to them even if I could. In other words: if I make a change that helps me, I want to make sure that I make that option available to everybody else, because quite frankly that's a big portion of the whole point of open source. The whole "scratch your itch" isn't just about scratching _your_ itch, it's about getting it (almost by mistake) fixed for a lot of other people too.
