The point here is to turn S into K symlinks for the is-disabled case.

That said, the above check is flawed, since it doesn't take into account
if the administrator has made custom changes, i.e. deleted symlinks
manually or added one manually. So I'd say we always need to check *all*
runlevels for existing symlinks and compare that with the expected set
of S and K symlinks.
