Raspberry PI + Extend SD card life

sudo swapoff --all

You must also prevent it from coming back after a reboot:

  • For Raspbian which uses dphys-swapfile to manage a swap file (instead of a “normal” swap partition) you can simply sudo apt-get remove dphys-swapfile to remove it permanently. Best to remove because setting the CONF_SWAPSIZE to 0, as explained in this answer, doesn’t seem to work and still creates a 100MB swap file after reboot.

Directories in RAM

Highly used directories such as /var/tmp/ and possibly /var/log can be relocated to RAM in /etc/fstab like this:

tmpfs /var/tmp tmpfs nodev,nosuid,size=50M 0 0
