Place a microsd card in your desktop system and write the image.

In this instance, the microsd card is detected as sdd.

sudo dd if=2018-10-09-raspbian-stretch-lite.img of=/dev/sdd bs=4M

Initiate a rescan of the device.

su root -c 'echo 1 > /sys/block/sdd/device/rescan'

Edit config

Mount the RPi boot partition and make some changes.

su -m
mount /dev/sdd1 /mnt
vi /mnt/config.txt

Some example options for config.txt.


Enable network login for default user.

touch /mnt/ssh

Un mount the boot partition.

umount /mnt

Edit networking

Mount the system partition and set up networking. This will allow us to login after the Pi boots and finalise the set up.

mount /dev/sdd2 /mnt
vi /mnt/etc/network/interfaces
vi /mnt/etc/resolv.conf

Protect resolv.conf from errant applications which may wish to break it.

chattr +i /mnt/etc/resolv.conf

Un mount the system partition.

umount /mnt

Boot Pi and login to fix the O/S

It will take some time before the Pi is available, be patient.

ssh pi@X.X.X.X
sudo -s


apt-get update
apt-get dist-upgrade

Install sysvinit and restart

apt-get install sysvinit-core sysvinit-utils

Remove systemd

ssh pi@X.X.X.X
sudo -s
apt-get remove --purge --auto-remove systemd
echo -e 'Package: systemd\nPin: origin ""\nPin-Priority: -1' > /etc/apt/preferences.d/systemd

Disable undesired services

update-rc.d dhcpcd disable
update-rc.d motd disable
update-rc.d triggerhappy disable
update-rc.d cron disable
update-rc.d dbus disable
update-rc.d dphys-swapfile disable
update-rc.d ntp disable
update-rc.d avahi-daemon disable
update-rc.d bluetooth disable
update-rc.d plymouth disable
update-rc.d paxctld disable

Edit /etc/inittab and disable unnecessary gettys and reboot.

Set up swap

Because we disabled the useless swap generator, do it by hand.

swapoff /var/swap
dd if=/dev/zero of=/var/swap bs=4M count=512
mkswap /var/swap
echo "/var/swap none swap sw 0 0" >> /etc/fstab

Finish off

When we log in now we have a mean and lean linux installation but no service management. I prefer runit or you may prefer daemontools.

Set up runit/daemontools now as required and you are done.
