  that's fine, that's exactly what i want, an analogue to red hat's
"firstboot" feature. but i just ran across this in the
meta-intel-edison layer:

http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-edison/tree/meta-intel-edison-distro/recipes-core/post-install

which, if i read this correctly, also does what i want, i just need to
write a single script, post-install.sh.

  in any event, i realize there's more than one way to do this, i'm
just curious as to the recommmended way.
