Arch Linux

Please add the following patch to util-linux-2.20. The UUID detection function for sysfs breaks all the following, as it closes the file descriptor it gets handed. The patch fixes this behaviour.

Symptoms of this bug are failing nfs mounts.

+Subject: [PATCH] lib: do not attempt to close(0) in sysfs_deinit()
+
+If the 'open' fails we 'goto err' which runs 'sysfs_deinit()' on a 'cxt'
+which hasn't been fully initialised. The 'dir_fd' is still 0, so
+sysfs_deinit calls "close(0)".
