:facepalm:
Back on topic, I installed 2.8rc3 in a Fujitsu Siemens and it works like a charm.
The idea about using .dep files instead of symlinks is worth considering, IMHO. Downside is TCZ repo would be implied instead of refered directly.
Upside is that it would create and load something like 'bare.dep' as default, and provide room for future dialog at boot time if more than a personal .dep file us there, like 'vm.dep', 'webserver.dep', 'workstation.dep' and so on.
I am suggesting only, in fact I don't like 'bare.dep' because it would be easily confused with 'base'.
