I am developing a Debian GNU/Linux-based operating system/distribution. It's for visually impaired people. I took the standard Debian Live CD and built my distribution from a bare metal command line. Here are some features:Xfce desktop, heavily modified for the visually impaired;High contrast themes, icons and color schemes;Pre-configured Orca screen reader;An intuitive and simple screen magnifier;Virtual keyboard;Basic set of desktop applications, logos, wallpapers and bash scripts made by me.The system is pretty much ready and installable, in some kind of alpha state. I don't have a name for it yet, so I call it Redebian and use this name in my scripts. I will present it in a science and technology fair in my school in August (I'm currently in High School), so the project is very important for me.But one thing is bothering me: I don't know how to properly change my OS name from Debian to whatever its name will be. I googled for several days and got suggestions to edit /etc/os-release, /etc/issue and a few more files, but I am afraid to break the system. I'm using the official Debian repositories, so the release name is a very fragile factor.So my question is: what should I do to safely and properly change the name of my Debian-based operating system? For example, I want it to show Welcome to Redebian when the system is booting instead of Welcome to Debian. And I want the update-grub script to recognize the system as Redebian. I hope I made it clear and that someone can help me.
Fully rename my own GNU/Linux distribution
linux;debian
