I changed the naming convention for domain controller machines. They
are no longer "numbered," since the plan is to rotate through them
quickly. For each release of Fedora, we'll create two new domain
controllers, replacing the existing ones. Their names are now randomly
generated and contain letters and numbers, so the Blackbox Exporter
check for DNS records needs to account for this.
*mtrcs0.pyrocufflink.red* is a Raspberry Pi CM4 on a Waveshare
CM4-IO-BASE-B carrier board with a NVMe SSD. It runs a custom OS built
using Buildroot, and is not a member of the *pyrocufflink.blue* AD
domain.
*mtrcs0.p.r* hosts Victoria Metrics/`vmagent`, `vmalert`, AlertManager,
and Grafana. I've created a unique group and playbook for it,
*metricspi*, to manage all these applications together.
