Not only this. I want it on a RAID10 or RAID5 which goes faster than
my / that is hosted in a slower RAID1.

Maybe more simple, but then I will loose the advantages that I
already explained. And more importantly: I don't care simple.

This has nothing to do with the amount of space.
But if you want to go on that ground...

Today, you say 10GB. What about in 5 years? Can
you easily predict what will be my needs? I don't.

It depends what you do, I'd say. But yes of course, you'd have very few,
and even maybe zero once the system is setup, writes on /usr. But if
your computer has a lot of activities taking a lot of RAM, chances are
that stuff will be kicked out of the cache and get read again.

Isn't it because you are just becoming a bit lazy? :)

You could also have tell me to use just one single partition, and
that having a separate /tmp, /var and so on totally useless too.
We could argue as well during huge threads about it. :)
