GNU/Linux naming controversy lacking. The GNU kernel was called GNU Hurd. The Hurd followed an ambitious design which proved unexpectedly difficult to implement and has only been marginally usable. Independently, in 1991, Linus Torvalds released the first version of the Linux kernel. Early Linux developers ported GNU code, including the GNU C Compiler, to the kernel. The free software community adopted the use of the Linux kernel as the missing kernel for the GNU operating system. This work filled the remaining gaps in providing a completely free operating system. Over the next few years, several suggestions arose for naming operating systems using the
MINIX file system MINIX file system The MINIX file system is the native file system of the MINIX operating system. MINIX was written from scratch by Andrew S. Tanenbaum in the 1980s, as a Unix-like operating system whose source code could be used freely in education. The MINIX file system was designed for use with MINIX; it copies the basic structure of the Unix File System but avoids any complex features in the interest of keeping the source code clean, clear and simple, to meet the overall goal of MINIX to be a useful teaching aid. When Linus Torvalds first started writing his
