@whydoesnothingwork Thanks 🙏 Really good clear useful video of how modules are needed / used in #nixos with the #configurationdotnix to set ( #port #ipaddress etc. ) parameters using #execstart and #systemd for an application / #package #clouddns providing a #service .

TIL: If your /var/ partition fills up completely with #Docker images, you can use a different mount point for Docker data. Just change this line in /lib/systemd/system/docker.service (after stopping docker, and rsyncing all /var/lib/docker contents over)

ExecStart=/usr/bin/dockerd --data-root /media/dennis/64GB_SD_EXT4/docker -H fd:// --containerd=/run/containerd/containerd.sock

#ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

I ran into this issue with my #NVIDIA Xavier whose root disk starts with only 11GB free.
