+Subject: hooks/30-hostname: Exit with 0 if setting hostname is not needed
+
+If the hostname is already set before dhcpcd is started, `need_hostname`
+will hit the "No old hostname" case and will call `false` to return 1.
+`set_hostname` will return with the same return value. Then
+`30-hostname` will exit with the same exit value:
+
+```

+
+Return with value 0 in case setting the hostname is not needed.
