As we are facing massive rebuild times not only due to dependency updates
but also Solaris 11 I have some more radical ideas:

1. Isolated build environment

Now that Solaris 9 is gone we can clone fresh build zones and verify sufficient
setting of BUILD_DEPS.

2. Activate buildbot again

Compile in the background for dozens of auto-modified packages to see if it worked.

3. Enhanced package hierarchy

Add one more directory catalog/ in a package directory besides branches/, tags/ and trunk/
which contains a subdirectory for each catalog a package is in. This ensures easy
bugfixing in named catalogs and use auto-build packages for propagation in the catalog.

Thoughts?


Best regards
