Debian does clean /tmp at boot, though the FHS does recommend it. And there's nothing to stop us adding the following to post_mountall: rm -rf /tmp/user mkdir -m 0755 /tmp/user This gives us everything that /run/user gives us, without needing to touch /run. Note that the primary motivation for it being under /run AFAICT is that Fedora has pathological /tmp reaping behaviour enabled by default, so this is a workaround for their brokenness rather than there being an inherent need for it to be under /run. This workaround for self-inflicted brokenness does not apply to us. > If you think the XDG requirements are /wrong/, please take that up with the > XDG folks... I have already briefly discussed this with lennart, but IMHO the basic premise for this is flawed from the start, and having its persistence decoupled from the session with started it is fundamentally wrong. It means that you have at a stroke restricted the system from having more than one session for each user. Fine if you only have about GNOME, but otherwise it's not acceptable. Regards, Roger -- .''`.
