 srestegosaurio (on tchncs.de) | Okey. | 17:25:09 |
| srestegosaurio (on tchncs.de) | You mean doing steam-run bash -x steam? | 17:26:25 |
 K900 | No | 17:27:08 |
| K900 | You need to find the actual script that's running in the Steam container | 17:27:33 |
| K900 | It is in bubblewrap's arguments | 17:27:57 |
| K900 | As --symlink <something> /init | 17:28:07 |
| K900 | Oh actually | 17:28:23 |
| K900 | steam-run bash -x $(which steam) may work | 17:28:31 |
| K900 | Oh no | 17:28:53 |
| K900 | You need layers | 17:28:57 |
| K900 | steam-run sh -c 'bash -x $(which steam)' | 17:29:09 |
| srestegosaurio (on tchncs.de) | It might be that steam.sh is not executable? | 17:37:13 |
| K900 | Uhh, what | 17:37:21 |
| K900 | What steam.sh | 17:37:25 |
| srestegosaurio (on tchncs.de) | The on located under ~/.local/share/Steam. | 17:37:50 |
| K900 | Is your home directory mounted noexec or something | 17:38:06 |
| srestegosaurio (on tchncs.de) | My home dir is but not my persistent partition. | 17:38:29 |
| srestegosaurio (on tchncs.de) | It was working before, the only thing I changed is the impermanence version. | 17:39:09 |
| srestegosaurio (on tchncs.de) | But I fail to understand how could be producing errors if nothing else has broke. | 17:39:31 |
| K900 | I don't understand impermanence enough to tell you | 17:40:40 |
| srestegosaurio (on tchncs.de) | Afaik it is using systemd mounts to bindmount dirs currently. | 17:41:14 |
| srestegosaurio (on tchncs.de) | # /etc/systemd/system/home-srestegosaurio-.local-share-Steam.mount

| 17:42:18 |
| srestegosaurio (on tchncs.de) | Wait, it might be giving me issue now bc before I was using bindfs and now it is using proper bindmounts, so now it does not matter if steam.sh et al reside on an executable partition bc it is being executed from a noexec place. | 17:47:26 |
| srestegosaurio (on tchncs.de) | Fixed it. | 18:00:46 |
|  L joined the room. | 18:52:52 |

 ElvishJerricco | Anybody here doing VFIO stuff with NixOS? I'm writing a migration guide for systemd stage 1 and apparently a very common use case for preDeviceCommands is VFIO stuff. I want to figure out the best way to do that properly instead, but do not use VFIO myself. | 07:07:37 |
 Sandro 🐧 | I assume GPU and not network interfaces? | 10:27:17 |
| ElvishJerricco | In principle that would still be helpful. Figuring out how to do vfio at all with systemd stage 1 is step one. But yea ideally I'd figure out how to do it with a GPU | 10:35:21 |
| Sandro 🐧 | The only thing I know that uses vfio is microvm.nix for PCI devices and I think networking but that does it apparently in userland https://github.com/microvm-nix/microvm.nix/blob/main/nixos-modules/microvm/pci-devices.nix | 10:38:38 |

 codebam | does anyone know how to disable the shortcut to open big picture mode when you long press the home button on your controller? every time I turn the controller off I end up opening big picture mode | 18:35:18 |
