Looks like there was more information provided when this came down in Fedora. http://docs.fedoraproject.org/en-US/Fedora/15/html/Release_Notes/sect-Release_Notes-Changes_for_SysAdmin.html 3.2.2. /run directory Fedora 15 has a /run directory for storing runtime data. /run is now a tmpfs, and /var/run is bind mounted to it. /var/lock is bind mounted to /run/lock. Applications can use /run the same way as /var/run. Several programs including udev, dracut, mdadm, mount and initscripts used hidden directories under /dev for runtime data during early bootup before /var is mounted. However /dev/ is supposed to be used for only device nodes and there is consensus between major distributions to shift to using /run instead. Fedora 15 is leading this change. Details including the benefits are explained here. This change is compliant with the Filesystem Hierarchy Standard, which allows distributions to create new directories in the root hierarchy as long as there is careful consideration of the consequences. Co-author of the latest FHS specification has expressed support for this change. Lennart Poettering has filed a request to update the FHS standard to include this change as well. 3.2.3. /var/run and /var/lock /var/run and /var/lock are now bind mounted to /run and /run/lock from tmpfs, and hence emptied on reboot. Applications must ensure to recreate their own files/dirs on startup, and cannot rely that doing this at package installation will suffice. It is possible to use systemd's tmpfiles.d mechanism to recreate directories and files beneath /var/run and /var/lock on boot, if necessary. See tmpfiles.d(5) for details (http://0pointer.de/public/systemd-man/tmpfiles.d.html) and the conf files in /etc/tmpfiles.d for examples of such configuration. Fedora packaging guidelines for tmpfiles.d is at http://fedoraproject.org/wiki/Packaging:Tmpfiles.d. Modul prepared for check. RHEL6_7/system/RunFHS Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below.
