Most systems provide the full version number in the 'release' field and the kernel version in 'version'. Minix used to split the full version number between release and version which caused problems for pkgsrc and other applications. This patch brings Minix's uname in line with other systems such as NetBSD. It also brings the getty banner in line with NetBSD. Old Minix uname: sysname->Minix nodename->10.0.2.15 release->3 version->2.1 machine->i686 New Minix uname: sysname->Minix nodename->10.0.2.15 release->3.2.1 version->Minix 3.2.1 (GENERIC) machine->i686 Change-Id: I966633dfdcf2f9485966bb0d0d042afc45bbeb7d
