Comment 38 for bug 2065037

dmesg_v9_new.debug has:

```
[ 47.337075] systemd[1]: Setting '/proc/sys/kernel/printk_devkmsg' to 'on'
```

That matches roughly 47.314s (kernel) from systemd-analyze. So no need to redo v4_new.

v4_new shows 30 seconds of sleep and v9_new does not. Can you sprinkle the code with `cut -f1 -d' ' /proc/uptime` calls to figure out at which point the time is spent? For a baseline, add that call to the beginning and the end of configure_network. I would expect that configure_network takes > 30 seconds for v4_new and it should take ~30 seconds less for v9_new.
