Comment 54 for bug 2065037

I had to reboot my Main Workstation due to some GTK/Mate/Desktop Environment Issue (maybe related to NVIDIA Drivers ?).

Anyhow I took the opportunity to implement quickly the fixes we discussed:
- `/usr/lib/dhcpcd/dhcpcd-hooks/30-hostname`: `need_hostname || return 0`
- `/usr/share/initramfs-tools/scripts/functions` : `dhcpcd -1K --noipv4ll --noarp -t $ROUNDTTT -4 ${DEVICE:+"${DEVICE}"}`

Output of `systemd-analyze`:
```
Startup finished in 22.505s (kernel) + 50.381s (userspace) = 1min 12.887s
graphical.target reached after 50.366s in userspace.
```
