The mddc-add-block-sym program

+ mddc-add-block-sym is a helper script to create + symlinks at /dev/disk/by-*. +

Interface

     mddc-add-block-sym

+ mddc-add-block-sym takes no arguments. +
+ It reads the MDEV environment variable, + if it is empty it exits 100. +
+ It creates PARTUUID symlinks at /dev/disk/by-partuuid/, + using /sys/block to get the PARTUUID. +
+ It creates DISKSEQ symlinks at /dev/disk/by-diskseq/, + using /sys/block to get the DISKSEQ. +
+ It creates hardware ID symlinks at /dev/disk/by-id/, + using /sys/block to get the ID. +
+ It checks whether it can execute blkid. + If this is the case: +

+ It creates UUID symlinks at /dev/disk/by-uuid/, + using blkid to get the UUID. +
+ It creates LABEL symlinks at /dev/disk/by-label/, + using blkid to get the LABEL. +

Exit codes

+ 100 if a critical environment variable is missing. +
+ Since mddc-add-block-sym is an + execline + script, it exits with an approximation + of employed program that failed. +
+ mddc-add-block-sym mostly uses + execline + software, the exit behaviour of which can be looked up on + their respective pages. +
+ See also: + execline exit code handling. +

Options

+ There are no options to mddc-add-block-sym. +
