That said, Dan's advice is quite solid: have your mixed environment in a VM, chroot, or other virtual environment. When it gets into an unusable state (it very likely will at some point, especially as testing further diverges from stable), you can wipe it clean and start over. Just don't do it on your main workstation or server outside of some virtual environment. Regards, -Roberto -- Roberto C. Sánchez
