The specific situation was a boot time failure where /proc had failed to mount. So to enumerate the conditions and the result: 1) /proc is not mounted (or has failed to mount) 2) /etc/mtab is a symlink to /proc/mounts (or /proc/self/mounts) 3) /run is not in /etc/fstab 4) The directory /run exists on the filesystem In this situation 'mount /run' results in: mount: /run: mount failed: No such file or directory Obviously mount is referring to /etc/mtab not existing, so the error message at present is misleading. -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
