Perchun Pak	In reply to @lassulus:lassul.us 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 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?	10:08:26

lassulus	well I wanted to create it in the case where the table exists but the partition does not	10:11:55
lassulus	I will prepare a commit	10:12:02
lassulus	give me 5min	10:12:04
Perchun Pak	I already did everything with my disk, it is not a blocker for me	10:12:38
Perchun Pak	* I already did everything with my disk, it is not a problem for me	10:12:47
Perchun Pak	Just a thing I noticed	10:12:59
n3v3r_a9a1n	halo! has anyone achieved disko + nixos-anywhere + impermanence btrfs? (+sops)	10:13:01
Perchun Pak	In reply to @xxxcrow:matrix.org halo! has anyone achieved disko + nixos-anywhere + impermanence btrfs? (+sops) Vimjoyer did config for btrfs + impermanence, don't know about other things https://youtu.be/YPKwkWtK7l0?feature=shared	10:14:30
lassulus	hmm, indeed weird, that sgdisk exists with 0 on an error	10:20:57
n3v3r_a9a1n	In reply to @perchun:matrix.org 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	10:34:06
Perchun Pak	In reply to @xxxcrow:matrix.org 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
n3v3r_a9a1n	In reply to @perchun:matrix.org It backups all your data on every reboot. I can show you the folder structure when I arrive home 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"; }; }; }; }; }; }; }; };	10:36:46
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 https://gist.github.com/PerchunPak/0df4fa9117dfb036b0564a9f058f539c	10:39:49

n3v3r_a9a1n	i do: `nix run github:nix-community/nixos-anywhere -- --flake .#immortal root@192.168.1.100 --no-reboot`	10:44:32

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
n3v3r_a9a1n	In reply to @perchun:matrix.org Vimjoyer did config for btrfs + impermanence, don't know about other things 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

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

In reply to @lassulus:lassul.us
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

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?
