I am seeing this on status pages. Have been on several versions, but now on 6.16, I thought I'd ask:

MimeDetect is using the browser supplied filename for file extension lookups. It is strongly recommended that you install and configure the PHP Fileinfo Extension or the UNIX 'file' command to provide more accurate severside mime type detection.

Now, other than not knowing that server has an "r", what's the deal with this?

root@atlas:~# which file /usr/bin/file

Which path, presumably, PHP or Drupal would know or guess.

So why can't it find it?
