The attached patch proposes to select Apache MPM prefork by default. Since FreedomBox uses many PHP applications and PHP, at least on Debian, needs single threaded process. When switching to prefork MPM during the installation of PHP applications, Apache restart is requried disrupting connections to Plinth. So, select it by default. I have done the following tests on fully built image: - Apache should be running as MPM prefork - Plinth should be accessible. -- Sunil
