I've made an image of the normal Ubuntu MATE 16.04 for Raspbery Pi but using the f2fs filesystem. Everything else is identical to the normal image. Because you can not resize a f2fs filesystem you will need a NOOBS 8GB micro-sd card to use this image. This image may also work on other 8GB micro-sd cards.
The f2fs file system should extend the life of your micro-sd card. As a bonus, it is also often faster. It is purpose built for flash. I have found it to be very reliable.
The exact same install instructions apply. Basically download, and then:
sudo ddrescue -d -D --force ubuntu-mate-16.04-desktop-armhf-raspberry-pi-f2fs.img /dev/sdX
You can download the torrent from here:
