You can embed config file into the binary.

Could you please report those bugs to bugzilla? make sure you boot with:
linuxrc.debug=1 linuxrc.log=/lrc.log

Also there is a DVD media available, but it is not published yet. So
you can download it manually with:
osc getbinaries
openSUSE:Factory:PowerPC/_product:openSUSE-dvd5-dvd-ppc64le/images/local
