When you say full node, what do you mean?  

Like a full bitcoin node?  I'm currently running one on a RPi I set up the other day, that is running in nested Docker containers.  The blockchain data is being written to an external HD.

Same thing, any temp files/directories are always in tmpfs.  

    tmpfs           /tmp                  tmpfs   defaults,noatime,nosuid,size=100M 0  0
    tmpfs           /var/log              tmpfs   nosuid,nodev,mode=0755,size=50M   0    0
    tmpfs           /var/tmp              tmpfs   nosuid,nodev,size=10M   0    0

Roll

Here is an example:

    # reduce writes to SD card
    tmpfs           /tmp            tmpfs   nosuid,nodev,size=100M         0       0
    tmpfs           /var/log        tmpfs   nosuid,nodev,nosuid,mode=0755,size=50M        0           0
    tmpfs		/var/log/nginx  tmpfs   nosuid,nodev,nosuid,mode=0755,size=20M	0	0
    tmpfs           /var/tmp        tmpfs   nosuid,nodev,size=10M         0       0
    tmpfs		/var/www/  tmpfs  nosuid,nodev,mode=0755,size=10M   0    0
