That is such a good point
Preserving fire is a much under rated area of research.
I've done it, for days on end. Basically I took a leaf from ötzis book, and adapted it to my own circumstances. In my no-tools version I took a tube of birchbark from a rotting birch (karate kid style), stuffed some damp sphagnum moss into one end, added a smoldering F. fomentarius inside some more damp sphagnum moss, stuffed some more into the remaining end, and added a carry handle from spruce roots. Walk through the woods like some bushy choirboy, gently swinging it every now and then to improve airflow. Works even in pouring rain, redampen moss as needed, restart a new chunk of fungi when you get low. Extra benefit; no mosquitos.
