But lets see what awaits me with 2.6.30-rc1 update: root@amd:~# mount /data -oremount,noatime root@amd:~# mount /data -oremount,strictatime mount: /data not mounted already, or bad option ...oh no, my mount is too old. My mount seems to be up-to-date with debian testing. Should I have to install mount from sources just to keep the compatible system settings? There has to be a better way.
