Execution Trace (Node)

Node can provide an execution trace (using Go's runtime/trace) from startup until a set of CNs are initially reified (i.e. the WireGuard networks for the CNs are configured and Hokuto DNS is configured for them, if applicable).

Configuration

Set the QRYSTAL_TRACE_OUTPUT_PATH envvar for the output path of the trace. Note that the NixOS modules set PrivateTmp=yes on the systemd unit (e.g. if you set QRYSTAL_TRACE_OUTPUT_PATH=/tmp/qrystal-trace, then the trace would be in something like /etc/systemd-private-abc-qrystal-node.service-def/tmp/qrystal-trace).

Set the QRYSTAL_TRACE_UNTIL_CNS envvar to a JSON list of the CNs. Once all of the CNs specified in here are reified, the trace will be stopped (and saved). Example: ["examplenet","othernet"]
