From: Chern Lee To: "Eugene M. Kim" Cc: Subject: Re: docs/30675: `noatime' should be discouraged on /var as well Date: Wed, 19 Sep 2001 17:52:32 -0700 (PDT) A quick grep -Ri "atime" /usr/src/contrib/sendmail/ shows that sendmail does not use file atime's for any operations. Mail program often use *modification timestamps* (mtime), which is not changed by the noatime option. Generally speaking, mtime is updated every time a file's contents is changed, atime is changed whenever a file is accessed. If my memory serves me correctly, postfix does not make use of atime either--I safely run a postfix server with noatime enabled on /var. - chern To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-doc" in the body of the message
