Several weeks? The first mail was sent on January 7th, my first intervention about 'noatime' being the default was on the 9th and your mail is dated the 16th. I would suggest that you revise your implementation of access times. > I haven't seen anything in this thread that wouldn't be better placed in > tuning(7) or tunefs(8). It's not really surprising since, given what you said before that, it seems that you haven't really paid attention to the messages exchanged. > Security and forensics are good reasons to keep atime unchanged. Having access times maintained may occasionally provide a bit more information, especially against script kiddies. But if you think it's a reliable source of information, you're deluded. See my response to Lyndon about the general problem with access times. I also already talked about auditing's needs in my very first mail in this thread. > Any discussion regarding changes to it's current behavior seems folly or bikeshedding. About bike shedding, see my recent response to Mark, it applies to "folly" as well. > Apologies for the "attitude". Yeah. Most prompts imagined by Poul-Henning Kamp in his bikeshed email would have applied perfectly to your message.
