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.
