Mount point already in use - when adding subdomains

[2xmy]

Thank you very much for the answer. I need to mount in the same directory to get my system to work - which is no problem with domain aliases, but not with subdomains. Even after having read your link I think that is a bit strange?

If I manually go around it, the only problem will be, that the FTP-server might stop?

I can see that there are almost more activity in the german category than in all the other categories put together, so it might help to get my question translated.
