I am modifying a file utilizing puppet file\_line resource but each time puppet runs, its triggering a refresh even though no other change has been made after the first puppet run.

```
file_line { 'log_format_combined':
   ensure            => present,
   path              => '/etc/apache2/apache2.conf',
   line              => 'LogFormat "%a %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined',
   match             => '^LogFormat "%h %l %u %t ."%r." %>s %b ."%{Referer}i." ."%{User-Agent}i."" combined',
}

```

What can I do to only trigger a refresh if a change is made to the file?
