Try it, it's actually much harder than it seems. Like allmodconfig, it
handles the minimum hardware well, but it tends to handle the subtle
issues really badly.
Many config options cause *very* subtle failures that are almost
impossible to see. Like firewalls not loading correctly (and leaving
the machine completely open), or just stuff that you didn't happen to
test (USB sticks, printers, certain programs) not working. Not having
the right audit options will make things still "work", but you'll get
warnings at bootup, and who knows what that causes etc etc.
These kinds of things are exactly why I'd like to have a distro config.
