For me the gui should be also not a part of the toolchain. The toolchain 
should contain tools for building and running a system. The gui is used 
to visualize and debugging.

That was just an example on how metapackages should depend on each other.

I agree here. If one selects rock.core, all drivers (even unused) will 
be installed.

But there should be one metapackage (rock.minimal?) that only contains 
the packages from the infrastructure that every installation really 
needs, for example orogen, rtt, base-types, roby, syskit. Without them 
you cannot build and run any rock installation. All specific packages 
like drivers, image_processing and gui should be in their own optional 
metapackages.

By just using the minimal packageset I don't need to select all required 
packages manually and you are not forced to install optional packages.

Regards,
Christian
