The same twelve steps, with the difference that matters: the mesh composes its own user
list and at genesis there is none, so this carries the first one — the controller's
account at a bootstrap password, rotated with the store's and replaced by the
controller's own composition from its first start.
The server's settings and the user list are separate files in one directory. Separate
because the settings belong to whoever raises the server and the users belong to the
mesh; in one directory of necessity, because an include path resolves relative to the
including file's own directory, so an absolute one sends the server looking underneath
that directory and it refuses to start.
No `verify` in the TLS block. That makes the server demand a client certificate and
nothing in the mesh presents one — a host pins this server's exact certificate and
authenticates with a password.
The controller's permissions here are checked against what the controller derives, by a
test in its own repository reading this file. They are two statements of one fact, and a
template that granted less than the controller needs would produce a mesh that comes up
and is refused on its first act.
