 ===== BIOS configuration =====
 For booting fom emmc: XHCI enabled
+===== NixOS crypt setup =====
+Encrypted NixOS via standard installer by Nov.2022 (v22.05) but changed ext4 root filesystem to btrfs after installation.\\
+Before reboot you can unmount the new installation-system partitions. Then you can simply convert the ext4-filesystem with
+<code bash>
+btrfs-convert /tmp/newroot
+</code>
+With **blkid** you can get the new UUID for the converted logical volume and copy in hardware-configuration.nix file:
+==== hardware-configuration.nix ====
+<code bash>
+fileSystems."/" =
+    { device = "/dev/disk/by-uuid/d11cd5b3-8a41-42d0-b671-04efbdd8b18b";
+      fsType = "btrfs";
+      options = [ "subvolid=5" "subvol=/" ];
+      neededForBoot = true;
+    };
+  boot.initrd.luks.devices."luks-btrfs".device = "/dev/disk/by-uuid/085ffcdf-5a5c-43fc-9231-eed8b5d0bbd4";
+</code>
+changed also
+==== configuration.nix ====
+added here also (maybe not needed?)
+<code /bash>
+  boot.initrd.supportedFilesystems = ["btrfs"];
+</code>
+After changing the config, you have to run **nixos-rebuild boot** and **nixos-rebuild switch**
