Indeed systemd-tmpfiles-clean.service does not read this, and I'm really not sure whether this should be put back. Preserving files in /tmp is counterintuitive, a recipe for filling up the disk, does not meet user expectations when rebooting, is not intended by the FHS (http://www.pathname.com/fhs/pub/fhs-2.3.html#TMPTEMPORARYFILES), and that option can never work reliably: If you enable tmp.mount or otherwise make /tmp a tmpfs this option cannot work.
If you really don't want to clean /tmp you can do "sudo systemctl mask systemd-tmpfiles-clean.service", but I highly recommend *not* to do this. We might add a comment to rcS that this setting does not work under systemd and is discouraged? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1444958 Title: STC830:Brazos:br311p06: file(s) are deleted from the /tmp after each reboot on Ubuntu OS Status in systemd package in Ubuntu: Triaged Bug description: == Comment: #0 - Application Cdeadmin <cdead...@us.ibm.com> - 2015-04-16 01:55:24 == ==== State: Open by: mpham on 14 April 2015 14:26:40 ==== Problem Description: ==================== File(s) are deleted from the /tmp after each reboot on Ubuntu OS.
