+#   - Checks out and re-using a local mirror for your kernel tree
+#   - Looks for a defconfig in kdevops to use for your kernel tree
+#   - Sets up CI metadata for kdevops-results-archive
+#   - Ensures your kernel tree at least builds with defconfig
+#   - Brings up target DUTs nodes
+#   - Installs your Linux kernel tree on them
+#   - Builds all of your test requirements for your Linux kernel tree
