By 1990 we had either found or written all the major components except one&mdash;the kernel. Then Linux, a Unix-like kernel, was developed by Linus Torvalds in 1991 and made free software in 1992. Combining Linux with the almost-complete GNU system resulted in a complete operating system: the GNU/Linux system. Estimates are that tens of millions of people now use GNU/Linux systems, typically via GNU/Linux distributions. The principal version of Linux now contains non-free firmware &ldquo;blobs&rdquo;; free software activists now maintain a modified free version of Linux, called  Linux-libre.
