You may remember when I originally redesigned the one-click installer for hackweek in 2008. Well, for this recent Novell/SUSE hackweek, I spent some time to slightly redesign and expanded on how the one-click installer should work. Will Stephenson also started working on an implementation, too.
Here’s my new one-click mockup (click on the picture to view at full size):
The text on the page should be pretty self-explanatory. Ideally, this would be implemented in a simple graphical client using PackageKit (and PolicyKit).
I believe the openSUSE Build Service (think of it as the “Open Build Service”, since it can produce packages for all the popular distros) even supports multiple repositories in one YMP (but I may be mistaken here), so using it with the OBS would be a fantastic way to easily build your software for multiple distributions (which you can do right now) and make it a snap click for everyone to install your software. Something like this could turn the entire web into an “app store” for Linux, and software could be easier to install than on any other platform, if implemented correctly.
Oh, and you can also download the SVG source (to be edited in Inkscape). It uses the Droid Sans font — be sure to have it installed.
