disko

Btw, I don't know if it is intended, but this command returns exit code 0 when partition exists
https://github.com/nix-community/disko/blob/0a17298c0d96190ef3be729d594ba202b9c53beb/lib/types/gpt.nix#L158
Should I open an issue on GitHub?

10:00:59

hmm, what is the problem?

10:02:55

ah maybe an ! is missing

10:04:51

but not sure how it even gets to that point, since it will skip the whole if statement if a table exists on line 156

10:06:21

I am not familiar with the code, but this line has 3 possible states (from my understanding)
- partition table does not exist
- partition does not exist
- partition exists

In bottom two sgdisk exits with 0 code, but in first with some other (don't remember exactly). Though if partition table doesn't exist, it will be created on top of the script

10:06:40

but not sure there is a scenario where a partition table does not exist but a partition?

10:07:33

either way, the code doesn't do whats intended :)

I deleted the part that created the partition table, that's how it did for me

So if the scenario where sgdisk exits with non zero doesn't exist, why is there an if statement?

* I deleted the part that created the partition table, that's how it did for me (not saying you should support this use case)

10:09:07

well I wanted to create it in the case where the table exists but the partition does not

10:11:55

I will prepare a commit

give me 5min

I already did everything with my disk, it is not a blocker for me

10:12:38

* I already did everything with my disk, it is not a problem for me

10:12:47

Just a thing I noticed

10:12:59

halo! has anyone achieved disko + nixos-anywhere + impermanence btrfs? (+sops)

Vimjoyer did config for btrfs + impermanence, don't know about other things

10:14:30

hmm, indeed weird, that sgdisk exists with 0 on an error

disko has gone crazy, or me?

                content = {
                  type = "btrfs";
                  extraArgs = ["-f"];
                  subvolumes = {
                    "/root" = {
                      mountpoint = "/";
                      mountOptions = ["compress=zstd" "noatime"];
                    };

mounts / in /root

It backups all your data on every reboot. I can show you the folder structure when I arrive home

10:35:16

so, i can find all the stuff in /root directory

i mean, it's not even that much of impermanence, but really about disko

10:36:14

ok, this is the drive:

            luks = {
              size = "100%";
              content = {
                type = "luks";
                name = "nvme-crypt";
                # disable settings.keyFile if you want to use interactive password entry
                #passwordFile = "/tmp/secret.key"; # Interactive
                settings = {
                  allowDiscards = true;
                  #keyFile = "/tmp/secret.key";
                };
                #additionalKeyFiles = ["/tmp/additionalSecret.key"];
                content = {
                  type = "btrfs";
                  extraArgs = ["-f"];
                  subvolumes = {
                    "/root" = {
                      mountpoint = "/";
                      mountOptions = ["compress=zstd" "noatime"];
                    };
                    "/home" = {
                      mountpoint = "/home";
                      mountOptions = ["compress=zstd" "noatime"];
                    };
                    "/nix" = {
                      mountpoint = "/nix";
                      mountOptions = ["compress=zstd" "noatime"];
                    };
                    "/persist" = {
                      mountpoint = "/persist";
                      mountOptions = ["compress=zstd" "noatime"];
                    };
                    "/log" = {
                      mountpoint = "/var/log";
                      mountOptions = ["compress=zstd" "noatime"];
                    };
                    "/swap" = {
                      mountpoint = "/.swapvol";
                      swap.swapfile.size = "8G";
                    };
                  };
                };

          };
        };
      };

When you're booted into the system, root is in /. When you mount the disk, structure is something like
```
- nix/store
- old_roots
- $(date) # older than 30d are automatically deleted
- root
- and some fourth folder name of which I completely forgot
```

Fourth is persist

Btw, here is how you can use it with luks
