Comment 30 for bug 2065037

Alright ...

So I issued:
- `apt-get install --reinstall initramfs-tools-core`
- `apt-get install --reinstall dhcpcd-base`

v4_new:
- applied `need_hostname || return 0` in `/usr/lib/dhcpcd/dhcpcd-hooks/30-hostname`
- issued the usual `update-initramfs -k all -u; update-grub; update-initramfs -k all -u; update-grub; reboot`

v9_new:
- same as `v4_new` with respect to `need_hostname || return 0` in /usr/lib/dhcpcd/dhcpcd-hooks/30-hostname
- in `/usr/share/initramfs-tools/scripts/functions` change `dhcpcd -1 -t $ROUNDTTT -4 ${DEVICE:+"${DEVICE}"}` to `dhcpcd -1K --noipv4ll -t $ROUNDTTT -4 ${DEVICE:+"${DEVICE}"}`
- in `/usr/share/initramfs-tools/scripts/functions`remove function call(s) to `_set_available_devices_to_up`
