Debian Is the Most Important Linux
inkscapee writes "Without Debian we are nothing. Debian is the most influential and important Linux, and is unique for being the largest, oldest, 100% non-commercial community-driven distro. '...just under 63% of all distributions now being developed come ultimately from Debian. By comparison, 50 (15%) are based on Fedora or Red Hat, 28 (9%) on Slackware, and 12 (4%) on Gentoo.'"
Google no longer maintains the code they previously contributed to the Linux kernel as part of their Android effort, creating a separate version or fork of Linux. Android's mobile operating system is based upon a modified version of the Linux kernel. It is not linux.
