In a 2002 analysis of the source code for Red Hat Linux 7.1, a typical Linux distribution, the total size of the packages from the GNU project was found to be much larger than the Linux kernel. Later, a 2011 analysis of Ubuntu's "Natty" release (a popular Linux distribution) main repository found that 8% to 13% of it consisted of GNU components (the range depending on whether GNOME is considered part of GNU), while only 6% is taken by the Linux kernel (9% when including its direct dependencies). Determining exactly what constitutes the "operating system" "per se" is a matter of continuing debate.
