Thank you BrianW for referring to my question.
For now, I wrote the Rachel-Pi img to an external HDD then accessed it from a Linux PC and copied the var/www/ folder to the local drive. Now, I will install Apache, PHP and SQL on that Linux and put the Rachel content in the www directory and serve the content from there.
What is still missing is the Rachel Plus features I mentioned in my old post.
jfield in this post New RACHEL-Pi image in the works said they are working on putting Rachel Plus features in the Rachel-Pi version. I think that’s great news and would be even better if there is a standalone version for PC based servers.
