1GB distro to display a full screen browser seems a bit excessive Edit: there is a lite version at 557MB, didn't notice at first due to it having two dates in the name
I don't understand the effort here. Making an image implies supporting it; does the author really think it's going to be worth his time to "support" what is surely a couple of bash scripts wrapped up in 600MB of OS? It seems like a simple how-to blog post would have been more appropriate.
So on a windows or mac machine (or pretty much any OS that can handle an SD card in the first place), you can write the image, edit the settings on the card, then stick it in the pi & have it up and running. The methods that most of us would use to do this manually, are near impossible to preflight from an OS that doesn't support ext2/3/4.
