BTRFS in LUKS?

[RaitoBezarius]

Hi there,

Going through the code and the examples, I'm not sure BTRFS in LUKS layout is supported with that, is this intentional? Can I send a PR?

Thanks a lot for the amazing tool!

that should just work. I guess you could add an example so it's more clear.

the type luks has a content option. which is of type deviceType. deviceType also includes btrfs

[RaitoBezarius]

luks.content = {deviceType = "btrfs"; } and how can I specify further stuff like subvolumes, etc. ?

ah, the btrfs support is not as advanced as people wanted it to be, right now I just support a list of subdirs. A full example would be like this:

{ disks ? [ "/dev/vdb" ], ... }: {
  disk = {
    vdb = {
      type = "disk";
      device = builtins.elemAt disks 0;
      content = {
        type = "table";
        format = "gpt";
        partitions = [
          {
            type = "partition";
            name = "ESP";
            start = "1MiB";
            end = "128MiB";
            fs-type = "fat32";
            bootable = true;
            content = {
              type = "filesystem";
              format = "vfat";
              mountpoint = "/boot";
            };
          }
          {
            name = "root";
            type = "partition";
            start = "128MiB";
            end = "100%";
            content = {
              type = "luks";
              name = "crypted";
              content = {
                type = "btrfs";
                mountpoint = "/";
                subvolumes = [
                  "/home"
                  "/test"
                ];
              };
            };
          }
        ];
      };
    };
  };
}

so? does it work?

FWIW btrfs as content of a luks container in a mdraid is working
