* Update golang.org/x/sys/unix This allows to use simplified string conversion of Utsname members. * Simplify Utsname string conversion Use Utsname from golang.org/x/sys/unix which contains byte array instead of int8/uint8 array members. This allows to simplify the string conversions of these members.
