Since lib.mdDoc is already defined as just id, this commit is a no-op as far as Nix (and the built manual) is concerned.

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.
