[systemd-devel] Starting a service before any networking

I'm sure this is trivial but I've gone round in circles without success. I have a script which reads from an SQLite database and generates various system configuration files - at the moment these are dhcpcd.conf and wpa_supplicant.conf but this might grow in future. As such the only dependency th

[systemd-devel] How to get Credential into Environment variable?

Hi all,     I'm not quite grasping something here... I've just learned about `systemd-creds` and now trying to utilize it with a service which depends on a secret stored in an environment variable (or passed as a CLI option). Normally I could use a line like: `Environment=SEC=1234` Now I've: 1

Re: [systemd-devel] Starting a service before any networking

Depends on what exactly runs dhcpcd and wpa_supplicant. Is that done by networking.service (ifupdown)? NetworkManager? Are they standalone services? I would generally expect Before/Wants=network-pre.target to work, but that relies on your network services themselves being set up correctly – they t

[systemd-devel] udev database cross-version compatibility

Hello, Back in 2014 and again in 2020, there were discussions on the mailing-list related to udev database version safety. This was important to know if libudev from a container could access to /run/udev/data files safely. Given then libudev and systemd-udevd would be potentially different vers
