* container_update_resources.go: it is Windows and Linux that need special handling * local*.go: all platforms use the same list of tasks * temp_unix.go/temp_unsupported.go: Darwin is a Unix * util_unix.go/util_unsupported.go: use generic unix tag The only user-visible effect of these changes is that tempMountLocation is now properly handled on Darwin Signed-off-by: Marat Radchenko <marat@slonopotamus.org>
