boot.initrd.systemd.repart.discard

Controls whether to issue the BLKDISCARD I/O control command on the space taken up by any added partitions or on the space in between them. Usually, it's a good idea to issue this request since it tells the underlying hardware that the covered blocks shall be considered empty, improving performance.

See systemd-repart(8) for details.
