Linux Disable /var Access Time Updates ( noatime )

in Categories , , , , , last updated November 27, 2009

I‘ve configured and mounted /var for squid caching and other purposes under Linux. I’ve noticed that the Linux file system keeps records of when files are created, updated, and accessed. My /var is exclusively used for caching purpose and I do not want to waste disk I/O while updating last-time-read attribute during reads and writes to files. How do I disable access time updates for /var partition?
