+# It is possible to select a specific persistent worker by label. Refer to the
+# Cirrus CI docs for more details.
+#
+# Generally, a persistent worker must run Ubuntu 23.04+ or Debian 12+.
+# Specifically,
+# - apt-get is required due to PACKAGE_MANAGER_INSTALL
+# - podman-docker-4.1+ is required due to the use of `podman` when
+#   RESTART_CI_DOCKER_BEFORE_RUN is set and 4.1+ due to the bugfix in 4.1
+#   (https://github.com/bitcoin/bitcoin/pull/21652)
+# - The ./ci/ depedencies should be installed:
+#   apt update && apt install screen python3 bash podman-docker curl -y
+#
+# The following specific types should exist, with the following requirements:
+# - lunar: For a machine running the Linux kernel shipped with Ubuntu Lunar 23.04. The machine is recommended to have 4 CPUs and 16 GB of memory.
