I am, as a matter of fact, subscribed to the FHS list.  If you read
the specification, you'll see that it does not in any way require
/usr to be a *mountpoint*; it can be located on the root filesystem
without any problems.  It's actually the default partitioning method.

Do you have any concrete reasons to have /usr separate from / ?

It may be instructive to read
http://lists.debian.org/debian-devel/2011/01/msg00152.html
and the rest of the thread it is in.

Also note that in jessie, I plan to mount /usr in the initramfs
(the patches are already written) and to deprecate a separate
/usr.  This will make /usr available from before init starts
(the immediate goal), and potential unification of / and /usr
further down the line (jessie+1 or later).
