For example, falling back to anything under $HOME will fail for nfs-mounted home, I believe. The requirements for XDG_RUNTIME_DIR are actually quite difficult to fill without specific distribution support. Especially the following: The directory MUST be on a local file system and not shared with any other system. The directory MUST by fully-featured by the standards of the operating system. More specifically, on Unix-like operating systems AF_UNIX sockets, symbolic links, hard links, proper permissions, file locking, sparse files, memory mapping, file change notifications, a reliable hard link count must be supported, and no restrictions on the file name character set should be imposed. - http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html Therefore we want the user to explicitly shoot himself in the foot if they have to. We actually used to have a fallback for XDG_RUNTIME_DIR being unset, and it only caused confusion.

[Bug 1058211] Re: weston does not fallback gracefully if $XDG_RUNTIME_DIR is not set
My interest in this bug is resolved with ubuntu-desktop now having a dependency on libpam-xdg-support. Is there any real chance anybody here is going to do anything on what the summary was changed to, the lack of fallback if $XDG_RUNTIME_DIR is not set, especially now that it will be set by default for everyone due to the above, or should it be closed won't fix? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1058211 Title: weston does not fallback gracefully if $XDG_RUNTIME_DIR is not set To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/weston/+bug/1058211/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Is that a personal opinion No, this is the whole reason pam-xdg-support was written in the first place.

[Bug 1058211] Re: weston does not fallback gracefully if $XDG_RUNTIME_DIR is not set
I am not sure what good fallback location is. Check the behavior of e.g., nautilus or dconf for comparison. I believe they fall back to something under the user's homedir - that's not guaranteed to be local, but it's guaranteed to exist and be writable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1058211 Title: weston does not fallback gracefully if $XDG_RUNTIME_DIR is not set To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/weston/+bug/1058211/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Great, thanks. In that case I'm fine with weston having no recommends for libpam-xdg-support.
