<1> We wired the system property provider directly, without reading it at configuration time.

With this simple change in place we can run the task any number of times, change the system property value, and reuse the configuration cache:

	// h2transport (via onceSetNextProtoDefaults)
	nextProtoOnce      sync.Once
	h2transport        h2Transport // non-nil if http2 wired up
	tlsNextProtoWasNil bool        // whether TLSNextProto was nil when the Once fired

	// ForceAttemptHTTP2 controls whether HTTP/2 is enabled when a non-zero
	// Dial, DialTLS, or DialContext func or TLSClientConfig is provided.

	// Do the part that isn't allowed to have write barriers.
	wirep(pp)

	// Have p; write barriers now allowed.

	// Perform deferred mcache flush before this P can allocate
	// from a potentially stale mcache.
	pp.mcache.prepareForSweep()

	trace := traceAcquire()
	if trace.ok() {
		trace.ProcStart()
		traceRelease(trace)
	}
}

        // The user home dir is not wiped out by clean. Move the daemon working space underneath the build dir so they don't pile up on CI.
        // The actual daemon registry dir will be a subfolder using the name of the distribution.

//
// Likewise, if the handler didn't set a Content-Type, we sniff that
// from the initial chunk of output.
//
// The Writers are wired together like:

//  1. *response (the ResponseWriter) ->
//  2. (*response).w, a [*bufio.Writer] of bufferBeforeChunkingSize bytes ->
//  3. chunkWriter.Writer (whose writeHeader finalizes Content-Length/Type)
