"By this time, summer of 1991, we had both started posting to Usenet. In
August, Linus mentioned his kernel project on comp.os.minix for the
first time. Later on, he decided to make the code available, and got one
of the admins of ftp.funet.fi to put it there. For this, the project
needed a name. Linus wanted to call it Freax, but Ari Lemmke, the
ftp.funet.fi admin, decided to call it Linux instead. You can find the
Freax name in the Makefile of the earliest Linux releases."
