Probably.  Sorry.

We're not proposing to updating the distribution, we're proposing
updating a single service.  The point of using -s is to find out if
updating the service is going to have an impact on other services,
especially low-level ones that many services depend on.

I don't think anything like that has been established.  A separate
utility was having issues with malloc, not the printer daemon or
drivers.

But if that is the case, yes, David would need to revert glibc, and
this would show up in apt-get -s.  He would then post (well, more
likely he'd say "uh-uh, I'm not touching that!") "should I revert
glibc?" and we'd say (in 4-part harmony) "No!  Don't touch that!"

Sure, this is not something that I'd advise him to just randomly
experiment with.  But he's here because he either wants to or is
financially or otherwise constrained.  Either way, he'll be better off
if he learns to do this stuff.

Jim may be right that he should back everything up.  But he should be
backing up anyway.
