avoiding emsecondstage in crush for second target board

[hoefle marco <marco.hoefle@nanotronic.ch>]

Hello,
right now we have our application ported to emdebian crush on our intel
pxa board. The application consists of 23 emdebianised packages.
Until now I copied the emdebian packages to our board (or to the NFS
tree) and used dpkg -i *.deb on the target to install or update our user
application. The emdebian root filesystem was mounted per NFS by the
target, so I have easily access with the development PC.
If I want to make an updated flash image to give it to our tester who
has another board I used the NFS tree as the source of mkfs.jffs2.
However, until now it is always necessary to physically execute dpkg -i
on the board. Is there a way to update the NFS tree with a new emdebian
package without executing dpkg on the target?
Some developers might not have a target board but the "golden" root
files system (which was already configured with emsecondstage) as a sub
directory on their development PC.
Any hints are very appreciated.
Marco
