From my experience. Swap space on a SD Card is considered as not trustworthy and it also slows down the installation process.

• disable any boot to desktop in raspi-config, this saves valuable memory.

• disable unnecessary autostart executions

• do the most critical installation (for me rethinkdb) first

• write an installation script, this makes it easier to start from a bare img if you have to start again. Also it allows you easily to change the order and retry the installation.

• save your SD after each crucial step to an img/after the installation

I copy my installation script in here, maybe you can use it, if not the important steps can be extracted from the script. Please let me know if you need some explanation to one of the steps.

You have to set YOUR_SSID and YOUR_PASSWORD to include your Wifi. Copy this script in a new file: nano /etc/S99rc.installer and add a file with echo "start">/home/pi/installscript.status.

I started in the middle with applying this script, so no warranty that this works, maybe some adaption is necessary.

#RASPI INSTALLATION SCRIPT

  counter=$((counter+1))

  if [ "$counter" -gt "100" ]

    Failure
  fi

EDIT: You have to remove temporarily, the exit 0 in the comments of /etc/rc.local otherwise sed -i '/exit 0/i\/etc\/S99rc.installer' /etc/rc.local will be inserted after each exit 0. Or change the script accordingly: https://stackoverflow.com/questions/29256795/how-to-insert-a-line-before-the-first-and-last-matching-pattern-using-sed
