With a config like
{
networking.interfaces."lo".ip4 = [
{ address = "10.8.8.8"; prefixLength = 32; }
];
}
a nixos-rebuild switch would take a long time, and you'd see:
$ systemctl list-jobs
JOB UNIT TYPE STATE
734400 network-interfaces.target start waiting
734450 sys-subsystem-net-devices-lo.device start running
734449 network-link-lo.service start waiting
and:
systemd[1]: sys-subsystem-net-devices-lo.device: Job sys-subsystem-net-devices-lo.device/star>
systemd[1]: sys-subsystem-net-devices-lo.device: Job sys-subsystem-net-devices-lo.device/star>
systemd[1]: Timed out waiting for device sys-subsystem-net-devices-lo.device.
This removes the device dependency for `lo` and fixes this bug.
