[Nix-dev] how to set the prefered IO scheduler for a disk on nixos ?

[Tomasz Czyż]

you could do something like

systemd.services.set-up-disk-io-scheduler = {
  wantedBy = ["networking.service"]; # this is just an example, you need to
find some boot service which is loaded at the beginning, you probably can
also wait for device mount or other event
  script = "set you scheduler here";
}
