Vimjoyer did config for btrfs + impermanence, don't know about other things
https://youtu.be/YPKwkWtK7l0?feature=shared 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 |
| n3v3r_a9a1n | so, i can find all the stuff in /root directory | 10:35:16 |

i mean, it's not even that much of impermanence, but really about disko | 10:36:14 |
| n3v3r_a9a1n | 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";
};
};
};
};
};
};
};
};

| Perchun Pak | 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
``` | 10:37:23 |
| Perchun Pak | Fourth is persist | 10:38:10 |
| Perchun Pak | Btw, here is how you can use it with luks

ok, what do you thing the result of this would be? | 10:42:22 |
| n3v3r_a9a1n | i do:
nix run github:nix-community/nixos-anywhere -- --flake .#immortal root@192.168.1.100 --no-reboot
| 10:44:32 |
| n3v3r_a9a1n | then mount /dev/mapper/nvme-crypt /mnt | 10:44:50 |

then mount /dev/mapper/nvme-crypt /mnt or i shouldn't do it at all? | 10:50:02 |
 lassulus | Perchun Pak: I created this PR to fix the gpt behaviour: https://github.com/nix-community/disko/pull/595 | 10:51:22 |
| n3v3r_a9a1n | In reply to @xxxcrow:matrix.org
or i shouldn't do it at all? if i mount the way tutorials on impermanence+btrfs say, everything looks fine,but how do i take the snapshot | 10:54:15 |

https://youtu.be/YPKwkWtK7l0?feature=shared also, sorry if it's not true, but i think the way way he implements everything is not really ok
1st. https://discourse.nixos.org/t/what-does-impermanence-add-over-built-in-functionality/27939/16
2nd. it doesn't work with some stuff (can't remember what exactly either lanzaboote, or clevis, or something like that)
3rd. something else i forgot exactly what | 11:22:11 |

3rd. something else i forgot exactly what Yeah, it deleted all of my data if there wasn't something correct in the setup. Like no /persist/system or wrong permissions on /persist/home (in second scenario, home manager just failed to start completely). Though it is probably the fault of impermanence.
But for now, it works on my machine™. Feel free to send your final setup, I will happily steal it ;) | 11:57:22 |
| lassulus | whoops, I accidently ran sgdisk -o isntead -p on my main disk :D | 12:52:35 |
| lassulus | luckily I could recover it with disko | 12:52:46 |
| lassulus | but why are those 2 parameters (-p pronts, -o wipes) so close together on the keyboard :D | 12:53:07 |
| lassulus | * but why are those 2 parameters (-p prints, -o wipes) so close together on the keyboard :D | 12:53:14 |
| n3v3r_a9a1n | Quick questiono about disko and nixos-anywhere!
How do I skip disko in nixos-anywhere? | 16:01:36 |
| lassulus | Hmm you can't really. Maybe we should add a --stop-after-kexec parameter | 16:29:37 |
