/tmp/ is world writable, so there is no guarantee that one process will be the first to write to a file anyway. The case of "another process replaced it after deletion" is the same as "another process got there first on boot", and cannot be avoided. Anything using /tmp/ needs to be aware of this, and only use safe and non-guessable subdirectories, for example via mkdtemp, and need to use O_NOFOLLOW and friends when opening, and so on and so forth.
Or just do not use /tmp/ for functionality-critical files, and use RuntimeDirectory= instead which is managed correctly, without any hassle for the program. If any of the above is _really_ not possible, then such package needs to ship a drop-in in /usr/lib/tmpfles.d/ instructing sd-tmpfiles to leave a specific path or pattern alone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2088268 Title: systemd /tmp cleaning removes files that it shouldn't To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2088268/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
