Unfortunately, there is no easy way to do what you want because you
essentially have two separate, independent, and diverging histories.
Git doesn't offer functionality to push only part of the history, and
`.gitignore` is honoured when files are added, not when pushing.  Once
files have been added, `.gitignore` has no effect.

The best way to do what you want is to put the extra files from the
second case in a separate submodule, which can be pushed to server B but
not server A.  You may want to add a script to handle the case where
they do or don't exist and place them in the proper place via copy or
symlink if they're present.  You'll want to ignore them in the main
repo, though, since you don't want them to be checked in accidentally.
