Yes, /usr and /usr/obj are on different disks, noatime and async set on

I've certainly had far less problems with ccache than trying to use the
noclean options. To date I haven't had any issues using it (on 4 different
architectures), I think it is just when you try to customize things after
the first build that people have headaches... which makes no sense given
that it works off of the preprocessor, so any changes should show up as
different... but that's the only time I've had a problem with it...

At the time it was simply the most up to date 6.2 branch, guess I missed
that part in the copy/paste... I have nothing better to do later, so I'll
see how the time on current goes as well
