--mpi-install-scratch actually has MTT install (using
DESTDIR) into --scratch. Is that confusing? Though
--fast-scratch could also be misleading, as I could see a
user thinking that --fast-scratch will do some magical
optimization to make their NFS directory go faster. I guess
I'm done splitting hairs over --mpi-install-scratch :-)
