Mounting secondary (non-root) partitions with lazytime works fine, but / does not seem to retain the value from fstab - apparently because it is remounted rw during boot, and lazytime gets swallowed/undone. Same effect when trying to remount manually with lazytime: tux>findmnt / TARGET SOURCE FSTYPE OPTIONS / /dev/sda1 ext4 rw,noatime tux>mount -o lazytime,remount / tux>dmesg [ 5208.482505] EXT4-fs (sda1): re-mounted. Opts: (null) tux>findmnt / TARGET SOURCE FSTYPE OPTIONS / /dev/sda1 ext4 rw,noatime tux>mount --version mount from util-linux 2.26.2 (libmount 2.26.0: assert, debug) Newly mounting unmounted partitions works fine. Any ideas? Holger
