I need to support cases where /tmp is not tmpfs (e.g. current Fedora cloud images). The rationale is the way OSTree implements atomic upgrades and parallel OS installation involves having separate os roots, so by having /tmp -> /sysroot/tmp they're shared rather than separate per root. > I am pretty sure we should simply prohibit mounts on existing > symlinks. That would be one way to do it. I could figure something out on the ostree side to adapt, probably having custom units around /tmp. There's likely other people in the field though with mount points that are symlinks, and while they're clearly buggy it'd be rather unfriendly to just have them entirely break after upgrading systemd. Maybe a loud warning? _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
