Hammer now defaults to ‘noatime’, meaning the date and time of last access are not updated on every file action. Note that creation and modification date and time are still recorded. This will help with speed and disk activity.
This may cause a problem with any software expecting this to change – mutt, possibly? We will find out. This change was done after the 4.4 branch, so it’s not in the current release of DragonFly.
