Running on read-only SD cardI had a similar use. I'm using the Pi for narrowcasting web-pages in a building entrance. Powering the Pi via the USB-port on the TV. Mount / read-only. To make it powerloss proof I mounted / read-only by changing a line in /etc/fstab /dev/mmcblk0p2 / ext4 defaults,noatime,ro 0 1 Pretty simple. But some processes on a functional machine need to write. Mount /tmp in memory. Many things write to /tm
What is the optimum split of main versus GPU memory?
