Whether to enable support for Linux MD RAID arrays.
When this is enabled, mdadm will be added to the system path,
and MD RAID arrays will be detected and activated
automatically, both in stage-1 (initramfs) and in stage-2 (the
final NixOS system).
This should be enabled if you want to be able to access and/or
boot from MD RAID arrays. {command}`nixos-generate-config`
should detect it correctly in the standard installation
procedure.
