Looking into interesting GNU/Linux distributions and I found Ubuntu Christian Edition. Basically it’s Ubuntu LTS 22.04 with Christian software preinstalled, so read that as Bible and reference book software, DNS client for switching to filtered DNS providers, content blocking, church administration software, and scheduling software to limit when the computer can be used. This would be great for parents looking to protect their children from the horrors of what is available on the internet (there are things that are disturbing to adults and too horrible for young minds to see), or possibly for an adult trying to protect themselves because of a pornography or gambling addiction. So if this is appealing to you give UbuntuCE a try.
