Why not do something simple like leave all packages installing in the 
regular place, and running on the device something like

cp -a /usr /home/
mv /usr /usr2
ln -s /home/usr /usr
rm -rf /usr2

Every linux user who partitioned his disk wrongly has done something 
like this.

All this requires is that bootup scripts do not use files under /usr 
before /home is mounted, but that's supposed to be true anyway.
