Comment 42 for bug 201673

Colin:

Why dont you run updates for important base packages through a virtualbox installation of Ubuntu first. If it breaks you can just go back to save point X and fix it. Nobody will ever know ;)

The process could even be automated.
Like:
Only send the update if the vbox installtion reboots and shows X11 (gdm, kdm .. ) || login ( for a server ).

I think people do test/run LTS releases even in development. And this is not what i would call a confidence building exercise ;)
And we exspect bugs and breakage .. but not easily avoidable severe breakage :-P

But what do i know .. i just wanted to give my .02€
