It is, but you're also mounting /dev/fg/tmp on /tmp.

Actually, it's /etc/init.d/localmount, not bootmisc. Add a sleep command
just before No, you'de need to edit the bootmisc script and add a sleep
command just before

Ah, I thought only the 701 had the small SSD.

How? By spanning an LVM across the two, you have no control over which is
written to the most. I'd put / on the SSD then mount write-heavy
directories, like /var and /home, on the SD card. I'd also set $PORTDIR
to /var/portage (/usr is a daft place to put the portage tree anyway).
