 Alyssa Ross | It's ACPI — do aarch64 VMs use ACPI? | 12:16:38 |
 raitobezarius | I think I saw ACPI support for aarch64 in the kernel recently | 13:51:45 |
| Alyssa Ross | Oh yeah I'm not saying you can't do ACPI on aarch64 | 13:58:52 |
 antifuchs | I have a nixos test that tries to assert that a socket unit startup doesn't finish until a certain condition is met. If I do a machine.start() in the test code, the test waits forever until the socket's execstart finishes; is there a way to get backdoor.service not to depend on that socket being fully up? | 15:28:28 |

| antifuchs | trying to do it with the initrdBackdoor, but that feels kinda wonky | 15:33:05 |
| antifuchs | hrm, nope: now switch_root() hangs indefinitely (: | 15:35:14 |

Also IIRC libvirt does something like that already with /run/libvirt/firmware /run/libvirt/nix-ovmf, also /var/lib/qemu/firmware lately (which causes issues). | 18:11:12 |

It's ACPI — do aarch64 VMs use ACPI? Depends on who runs the VM I guess, the Hetzner Cloud ones do and they seem to be standard KVM with UEFI. | 18:14:17 |
| Alyssa Ross | You can do UEFI with devicetree though | 18:18:13 |
| Alyssa Ross | and I think that's what QEMU does | 18:18:16 |

Depends on who runs the VM I guess, the Hetzner Cloud ones do and they seem to be standard KVM with UEFI. Yeah, I think those are Ampere machines. I'm pretty sure mine has ACPI. | 18:29:31 |
| aloisw | I don't think the host hardware matters inside a VM. Unsure whether they use QEMU though. | 18:32:11 |
 Arian | Yeh seems qemu only does acpi for intel | 20:15:01 |
 ElvishJerricco | You could do systemd.services.backdoor.unitConfig.DefaultDependencies = false;. I tried to add that as a general thing one time but a bunch of tests broke so we undid that. But there's no reason the backdoor needs to wait for things like basic.target; those tests that broke just made assumptions about file systems already being mounted and stuff | 20:15:10 |
| Arian | Systemd folks told me vmspawn is basically untested and they never tried it on aarch64 | 20:15:27 |
| Arian | Mkosi qemu wrapper is also broken on aarch64 | 20:15:38 |
| raitobezarius | in true systemd fashion | 20:27:04 |
| antifuchs | oooh, is it basic.target that gets waited on there? I guess that's my culprit | 20:39:46 |

I made the mistake at looking all issues tagged with journal in the systemd issue tracker today

 magic_rb | so ive got a weird setup where i've got some disks on my server which are unlocked by me after the rest of the system boots up. therefore for example /mnt/disk1 wont be available until i unlock it. But when I do need the equivalent of machinectl bind uk3s /mnt/disk1/infrastructure/buildbot /data/buildbotto be ran. I'm not sure whats the best way to automate that in systemd. Maybe a service unit depending onmnt-disk1-infrastructure-buildbot.mount`? | 07:49:51 |
 gdamjan | automate what? | 15:58:25 |
| gdamjan | do you want to automate the unlocking?
there are some options here https://www.freedesktop.org/software/systemd/man/systemd-cryptenroll.html
with tpm2 or fido2 keys | 15:59:05 |

Yeh seems qemu only does acpi for intel I just tried it with TCG (on an x86_64 host) and the aarch64 guest does seem to have ACPI. | 17:14:08 |
