This adds another symlink for block devices: /dev/disk/by-diskseq/<number> where the number is the diskseq number as exposed by the kernel. It's useful for apps because they can use it to open a device by diskseq, in a way that is safe against device node reuse. I.e. if a device node path like this is passed to an app it could open the device node via the symlink and also parse the diskseq from the path. Once the device is opened it could compare the parsed diskseq with the one returned by BLKGETDISKSEQ on the open node, and if it matches they know they are talking to the right device. Fixes: #22906 |

Files in this directory contain configuration for systemd-udevd.service, a daemon that manages symlinks to device nodes, permissions of devices nodes, emits device events for userspace, and renames network interfaces. See man:udev(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of service itself. Use 'systemd-analyze cat-config udev/rules.d' to display the effective config.
