+Polish this a bit? It is not at all ready, and as I said earlier rpmlib is 
+broken. Please don't upload broken rpm packages to stable releases.

+Maybe the instructions should be:
+   - install dracut and kernel-desktop-latest from mga3
+   - reboot, make sure the "usrmove filesystem update"
+     kernel entry is chosen in the bootloader
+   - upgrade to mga3 as usual
+
+But that means a lot of things are still missing:
+   - dracut automatically including the conversion script
+     (only when needed?)
+   - automatic generation of the bootloader entry mentioned above
+   - removal of this bootloader entry after conversion
