Which I don't think is a good idea.

Well, let's say I have a big crash, and I want to recover, and I
need to access /etc/lvm/archive in a single user, with of course
my /usr in a bad state, and I wouldn't be able to mount it for
various reasons. Let's say, an HDD crash, which is very common.

If I need to have /usr mounted before init starts, then I'm more
or less dead, and I'll have to get a recovery CD / USB.

If I don't need /usr, everything is fine, I can boot into single
user mode, and repair.

Guess which situation I prefer?

Now, you tell me: what are the advantage of requiring having
everything in /usr exactly? I really don't get what the advantage is.

You must have not read some of my posts then.

Ditto. We did give concrete examples were recovery would be
harder with things in /usr rather than in /.

Also, please make the point into why having stuff in /usr is
to be preferred. Or is it that the *only* argument that you
have is that we are polluted by RedHat crap? If so, why
shouldn't we consider switching to an alternative of udev
like mdev, if its development goes on the right direction,
for Jessie?
