I embrace all the choices in the Linux world. I reject headlines like this. A decades old project like Debian is certainly already „made as it should be“, thank you very much. The „finally“ triggers me hard as well.
This work makes life easier to normal user to install debian like he/she does with other distributions, a work that should be already thought by official live maintainers due to the use case. Anyway for some reason (time, unable to see the use case, other) it was not done. No problem, now there is it.
Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
