The noatime option is also "good enough" for all other devices, since nothing on the box ever use atime (last accessed) for anything. I'd keep it simple and use noatime all the time.

Maybe there's a way to make this default in busybox or so, so that "mount device mountpoint" already assumes "noatime" as options?

Maybe simple(mdev-mount.sh)?


+		        FLAG="-o noatime"
-			if ! mount -t auto /dev/$MDEV "${MOUNTPOINT}" ; then
+			if ! mount -t auto $FLAG /dev/$MDEV "${MOUNTPOINT}" ; then
				rmdir "${MOUNTPOINT}"
