Quite a jump, not sure if I can get it smaller. Might be okay. After all , it's installing fonts for the rest of the world. Any ideas on how to reduce the size?

Please can you use the additional packages method instead?

Simply run the commands that don't fit into the pattern in the single base Dockerfile and let's retain only one template to avoid so much repetition.

I've gone ahead and made the changes myself, please see 5045f6d which you are welcome to continue using under the terms of the license.

Thanks for taking care of this - I had it on my todo list after the launch. Slowly catching up...

No worries, the license is and was always considered.
