During the installation process there is a "mandatory" data that can be unchecked. If some are unchecked, Koha will certainly not work as expected, we may want to force the insert of these .sql file (like sysprefs, notices, AV, etc.)
This is not trivial, we need to: 1. use the "mandatory" flag for all the different .sql files (not only frameworks), see $requirelevel in C4::Installer 2. use this flag in the template to remove the ability to uncheck those checkboxes 3. Remove the "Select none", "Select all" links if the "section" is mandatory
It would probably be a lot easier now that all the installers have the same file structure?
