With y I mean the vertical one.

Why does the y axis not start at 0?

With a rolling release distro you get the most recent upstream stable releases of all your software packages. There is really no blood involved. If you want the risk of blood, you need to install the bloody versions of upstream, i.e. newest git master.

Ubuntu et all on the other hand give you months to years old software. If you’re fine with that 🤷. And on big upgrade, they break install different software and tend to break stuff.

Idk what role hardware age has here.
