Hello,
I’d like to discuss the issue I faced. I don’t know should I fill issue report or make something else.
I made a decision to disable systemd-tmpfiles-clean entirely.
systemd-tmpfiles-clean by default configured to delete all files from /tmp with atime older than 10 days
after 15 min of system startup. That is regulated using tmpfiles.d rule and systemd-tmpfiles-clean.timer.
If machine has incorrect time set during boot (RTC not configured and no /var/lib/systemd/clock) and
later that time will be corrected using ntp, than systemd-tmpfiles-clean could delete all files and folder
(created withing 15 min, even opened and used at time systemd-tmpfiles-clean run) from /tmp directory.
I’d think about patching linux kernel to bind tmpfs atime to CLOCK_MONOTONIC. So atime wouldn’d be
affected by system time changes.
May be there is another solution for the issue.
Regards,
Alexander.
