  ah, got it.  i'd have to do something different as i currently do
*all* my work under my home directory, and i have scattered throughout
that the (sizable) directories that would make sense to move to the
SSD:

  * kernel source git clone
  * yocto/OE sources
  * several G dir of source tarballs used as premirror to yocto/OE

i suspect it's going to take some work just to figure out what's worth
moving to the SSD for extra speed.  i'm thinking that i can *start*
with what you did -- install to the SSD only, but put /home on the
second drive, then over time, decide what's worth migrating to the
SSD.
