Hi JamesK. I have helped maintain the build scripts at https://github.com/rachelproject/rachelpiOS. I am interested in seeing what you have done to improve the install process. Would it be possible to get a copy of your scripts? The link to the scripts at the top of this message is broken.
I have started modifying the rachelpiOS scripts to create a RACHEL build on top of the latest Raspbian image (2018-11-13). The existing scripts mostly still work. The main change I had to make was upgrading the scripts from php5 to php 7.0. Upgrading the scripts to php 7.0 was straight forward. However, I am concerned that the php code in contentshell has been written for php 5 and may have incompatibilities. Does your script use php 7.0? Jeremy, do you know if contentshell works properly with php 7.0? I have not found any issues in my initial quick tests, but it would be easy to miss something given the number of modules that could be affected.
Thank you so much for your help.
