Isn't the whole point of the check above that it now creates /etc/shells
if it didn't exist already?

That said, though, I'm still not entirely convinced that having
semi-random packages create a file that isn't mentioned in either FILES
or CONFFILES is a very good thing.  I'm also not totally clear on what
exactly the problem is that this set of patches is trying to solve: the
original commit message says that having nonexistent files named
in /etc/shells is "unreasonable" but doesn't provide any supporting
evidence for that assertion.
