According to #481653, relatime became the default option starting in 2.6.30. So hopefully partman desn't need to do anything. There is the page in manual partitioning that let you select options. Probably that page should indicate relatime is the default and also have the atime and noatime options available (I don't know if strictatime and nostrictatime are needed). -- Matt Taggart taggart@debian.org
