Hi again,

I looked a bit around and I found:
	- zypper
	- SMART
	- yum
	- apt-rpm

zypper/libzypp:
	- I tried to produce a static libzypp and hoped the compiler would
	  make it small, but I ended up in unresolved symbols in zypper and
	  didn't feel like continuing (and using -Wl,--begin-group.. )

SMART:
	- Oh, I assume that the python installation needed will bringt it to
	  the ballpark of libzypp/zypper

yum:
	- It is slow on my laptop, it will not fly on a 300Mhz device..


apt-rpm:
	- I stumbled over a port for rpm 5.x (rpm is such a mess), it
	  compiles (after patching out a json dependency, for a library
	  using Scons, highlighting broken scons support).
	- Even with things in the package we don't need the installed size
	  is < 2MB
	- genbasedir requires our RPMs to be in RPMS.all/, RPMS.armv5te/
	  format... and it is segfaulting.
	- I have attached my current bb file (against my companies bblayer)


anyone wants to jump in with trying to get apt-rpm to replace zypper? The
net-saving will be probably around 5-6MB...
