Devuan installation
Download
Visit https://devuan.org/get-devuan and locate the latest download image.
Fetch the image (Raspberry Pi Zero)
wget http://devuan.ksx4system.net/devuan_ascii/embedded/devuan_ascii_2.0.0_armel_raspi1.img.xz
Verify the file with the hash on the download page.
Decompress.
unxz devuan_ascii_2.0.0_armel_raspi1.img.xz
Install
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=devuan_ascii_2.0.0_armel_raspi1.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.
sdtv_mode=2 #dtparam=audio=on gpu_mem=16 dtparam=spi=on dtoverlay=spi-bcm2835 #dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25 dtparam=i2c_arm=on dtparam=i2c_vc=on #dtoverlay=w1-gpio,gpiopin=4 #dtoverlay=dht11,gpiopin=17
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. Use eth0 or supported WiFi adapter, Eg. BELKIN FD?????.
mount /dev/sdd2 /mnt vi /mnt/etc/network/interfaces vi /mnt/etc/resolv.conf
Un mount the system partition.
umount /mnt
Boot and login
Install Broadcom WiFi driver (if present)
To-do
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 reboot
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.
