Fedora does, fwiw: https://en.wikipedia.org/wiki/Fedora_Media_Writer
looks like it’s not just for fedora either. though that is still a little more complicated than an all in one ubuntu/mint/whatever installer. maybe someone should fork it and/or add that to this.
Fedora media writer is fantastic. You're right, it can either automatically download a fedora iso, or you can just feed it any image. Its so simple and handy for me, to the point a recent foray back to Debian was cut short because there was no included equivalent and the alternatives were just a hassle.
Although, the `cat liveimage.iso > /dev/sdX` tip mentioned in this thread is very handy and is probably enough for me. Anything I can do without a distro specific tool is a win.
For the tech, sure but for common people not so.
Why cannot Ubuntu just offer a download media creation tool like Windows does. Surely it's not that hard to couple dd with a batch gui.
