1. kernel 9% 2. gnu 8% 3. kde 8% 4,5 java, mozilla 6% 6. gnome 3%
If you combine gnu with gnome, we have 1. gnu 13% 2. kernel 9%
Also considering that java/mozilla are platform agnostic, the candidate names we have are
linux-gnu-kde OR gnu-linux(-kde)
If you are not running KDE, then gnu-linux seems like a very strong candidate for the name. The argument for calling it linux would revolve around the availability of GNU software on other non-linux distributions in some form or the other, thus making GNU a not very distinctive moniker. But MacOS/BSD doesn't really carry as much GNU as Linux distros do.
But the kernel is running all the time when booted up. A better argument would be that only a fraction of GNU software is active at any moment, so by percentage of GNU v/s kernel code executed in any given time interval, the kernel should win handily. This pie chart, as it stands, actually makes a case for calling it GNU\Linux.
