| Allen Liao | Hey guys, so I'm upgrading to 26.05.
I have a working luks setup with BTRFS subvolumes:
boot.initrd.luks.devices = {
cryptroot = {
device = lib.mkForce "/dev/disk/by-partlabel/disk-main-luks"; # conflicts with disko
allowDiscards = true;
};
cryptswap = {
device = "/dev/disk/by-partlabel/disk-main-swap";
allowDiscards = true;
};
};
disko config:
disko.devices = {
disk.main = {
type = "disk";
device = "/dev/disk/by-id/nvme-Samsung_SSD_990_EVO_Plus_1TB_S7U5NJ0Y750798J"; # /dev/nvme0n1
content = {
type = "gpt";
partitions = {
swap = {
content = {
type = "luks";
name = "cryptswap";
};
};
luks = {
size = "100%";
content = {
type = "luks";
name = "cryptroot";
content = {
type = "btrfs";
subvolumes = {
"@" = {
mountpoint = "/";
};
};
};
};
};
};
};
};
};
Do I add
fileSystems."/".device = "/dev/mapper/cryptroot";
``
and that's it? what about my swap?

 Enzime | I don't think you should need to set fileSystems."/".device, disko should automatically set that for you as long as you import the disko NixOS module and your disko configuration into your NixOS configuration | 19:36:46 |
