13I'll use Fedora Core OS, Matchbox and Terraform [fn:1], a match the requirements
14for Tectonic [fn:2]
15
16** Steps
17- Network Setup DHCP/TFTP/DNS [fn:3]
18- Matchbox [fn:4]
19- PXE network boot environment
20- Terraform Tectonic [fn:5]

33
34Run the provided [fn:dnsmasq] image with ~dnsmasq~ and PXE toolkit
35
36#+BEGIN_SRC sh
37docker run --rm --cap-add=NET_ADMIN --net=host quay.io/coreos/dnsmasq \
