Custom welcome.html is not displaying?

[ZimmerA]

I've set up a Galaxy container for testing and everything works brilliant so far.
The only thing that I can not seem to get working is the display of a custom welcome.html.

I've mounted a folder to /export/, placed a welcome.html with some basic content in there and restarted the container. However, I still get the default welcome.html displayed.

Here's what I have tried so far:

• use the original welcome.html and change a few words
• restart the Galaxy instance
• completly stop and restart the container
