Debian has automated build systems that build things on architectures that the developer doesn't have access to. We would have to build sage-the-library, upload it, wait for the automated systems to build it and distribute it, then if this is succesful on all architectures, only then can we upload sage-the-distribution to run the actual run-time tests. If any of these fail, we have to start the whole loop again.

Since 99% of the tests in Sage-the-distribution are actually for code that belongs in Sage-the-libary (and the other 1% is for SageNB), it is much easier to run the tests in Sage-the-library - one doesn't have to mentally context-switch so much.

These metapackages don't have test code for other packages. Their dependencies test themselves, and the metapackages "do" nothing.

OK thanks for the pointer. I'll write something to sage-devel.
