Use 'default.target' in systemd unit file example
Use 'default.target' in systemd unit file example

Previously, 'local.target' was used which is not going to work
out-of-the-box for lots of users.
The 'default.target' is the default unit systemd starts at bootup and
hence what most users would be expected to use.
