Hi Martin,

I forgot the on device upgrade issue when I made the patchset.
Thank you for pointing it out.

I did some tests. The on device upgrade did broke with opkg as the 
package manager. RPM does not have this problem.

I'll make a follow-up patch to fix this problem tomorrow.

Thanks a lot,
Chen Qi
