noatime means no record of access time:
http://tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/chap6sec73.html

Since on a Linux system files are written to almost every minute, recording
atime everytime an access occurs increases the disk I/O.

I need to know access times for some files so I don't quite like that. I use
relatime: http://kerneltrap.org/node/14148

Such tests like to assume a lot of things, so I don't like those either.
Anyway this isn't really a test, it's just a mockup a user put up because he
was asking for something similar and realised there was no answer.
