One of the odd things I&#x27;ve seen that marks a &quot;good&quot; admin from a &quot;bad&quot; admin is their reliance on md5s as a checksum for file differences for anything in bulk. It&#x27;s extremely rare to see a collision, but it definitely happens (I&#x27;ve seen it once after a decently sized config change. Nobody believed me :( ). That&#x27;s not to say it&#x27;s not a useful hash, just that it should be used with caution.
