@elvishjerricco:matrix.org	Now I have two other problems. For some reason the DHCP server built into networkd that I use on my pi router requires my networkd clients to have `dhcpV4Config.ClientIdentifier = "mac";` if I want static IPs to work. So now I have to configure that in initrd. For some reason `systemd-timesync.service` is failing in stage 2 now with `Failed to allocate manager: Permission denied`	06:44:28

@mlyx:matrix.org	Has anyone tested `boot.initrd.systemd.enable = true` in kexec initrd? Seems that it doesn't work. I don't know how to debug initrd. What's the reason? https://github.com/nix-community/nixos-images	10:15:21
flokli	mlyx: it's still marked as experimental. You might want to open a specific issue with what's exactly broken for you.	12:29:58
Paul Haerle	In reply to @mlyx:matrix.org Has anyone tested `boot.initrd.systemd.enable = true` in kexec initrd? Seems that it doesn't work. I don't know how to debug initrd. What's the reason? https://github.com/nix-community/nixos-images Not exactly what you are asking for but https://github.com/dep-sys/nix-dabei uses boot.initrd.systemd.enable (and the networkd PR) and kexecs into an initrd (without stage-2) with enough tools, you might at least find some inspiration there? W.r.t. debugging: one could increase log verbosity (see kernelParams in the repo), run a shell on console (e.g. https://github.com/dep-sys/nix-dabei/blob/main/modules/auto-installer.nix#L61) or just start sshd if networkd is included in your initrd :)	13:55:12

May I ask what is the trick to reduce the size of initrd compared to netboot?	14:14:26
Paul Haerle	In reply to @me:linj.tech great project! May I ask what is the trick to reduce the size of initrd compared to netboot? Thanks! Sure: There's no stage-2, so it's not a "real" nixos which gets booted but just an initrd where needed binaries and so on are added manually. Happy to go into details, but maybe switch to DMs for that so that we don't spam this channel to much with OT messages? :)	14:16:22
@me:linj.tech	thanks. will take a closer look at the code	14:20:00

@hexa:lossy.network	In reply to @elvishjerricco:matrix.org mlyx: You would make a new initrd systemd service that has `wantedBy = ["initrd.target"];`. You also want the service to be ordered after file systems are mounted, but if you don't have `DefaultDependencies=no`, then it'll have `After=local-fs.target` by default anyway. But eventually we're going to change it so systemd-initrd uses `initrd-fs.target` like we're supposed to, which services don't get ordered after by default so I tried building a unit like tihs	18:41:50
