We had a "mount -o remount,rw none /" that was setting back 'relatime', although we had set 'noatime' at initrd mount. Removing the word 'none' fixed it. Specifying a device (in this case 'none'), makes mount to forget previous device options. According to manpage, it says not to read fstab or mtab. But the effect is that of setting 'relatime', if it was mounted 'noatime.
