I'm interested into trying bcachefs with encryption using disko and I saw that there is a PR which is blocked because it should an abstraction for supporting multiple devices should be implemented before.
I also saw there is another PR for supporting subvolumes.
Would a PR where I try to integrate both the attempts together be appreciated? In terms of interface would you like something similar to the first proposal in this comment?

 disko.devices = {
    disk = {
      x = {
        type = "disk";
        device = "/dev/nvme0";
        content = {
          type = "gpt";
          content = {
            type = "bcachefs";
            label = "ssd.ssd1";
            pool = "rpool";
          };
        };
      };
      y = {
        type = "disk";
        device = "/dev/sda";
        content = {
          type = "bcachefs";
          label = "hdd.hdd1";
          pool = "rpool";
        };
      };
    };

    bcachefs_pool = {
      rpool = {
        type = "bcachefs_pool";
        mountpoint = "/";
        passwordFile = "secret.key";
        subvolumes = {
            "/home" = { };
            "/nix" = { };
            "/testpath" = { };
            "/testpath/subdir" = { };
          };
      };
    };
  };

I answered in nixos-anywhere, but I can also answer here

In reply to @lassulus:lassul.us
so I will try to think about that next
