I can recall that I used something like `PSEUDO_xxx=xxx PSEUDO_xxx=xxx 
smart(or rpm?) ... --data-dir=xxx <command>'. But I don't remember 
whether I tweaked something else. Sorry :(
That's really a long time ago and I didn't write a document at the time.

The rpm database is not usable. You do a query to list files that a 
package installed and you will find all the paths are not correct.

We are now working a new kind of SDK in OE. We call it extensible SDK. 
By design, its components could be updated/installed/removed using 
sstate objects. The task is not completed yet, but we are working on it.
