Keep it simple unless there's a strong reason not to. It is really hard to assess the costs of these two paths over all users and uses. I don't object to mounting all local in mountcritlocal (and I don't care if it is renamed to mounlocal). I don't want to commit that personally, since I don't want to bite off responsibility for fixing problems I didn't anticipate. Right now, mountcritremote comes before servers/etc. and the rest can happen later, in mountall. Right now for almost everyone mountcritremote does nothing. That does't have a compelling reason for change, so there's only risk of breaking things we don't understand, and I'm inclined to leave it.
