+# Service: icinga-stack
+#
+# Description: Installs and configures a full Icinga2 monitoring stack.
+# This script is designed to be easily adaptable for future OS releases.
+#
+
+# --- OS & Version Configuration ---
+# This section contains variables that may need to be updated for a new OS release.
+
+# Automatically detect the OS codename (e.g., "bookworm", "trixie")
+# This should work without changes on future Debian versions.
+OS_CODENAME=$(source /etc/os-release && echo "$VERSION_CODENAME")
+
+# Define the PHP version for the current OS release.
+# For Debian 12 (Bookworm), this is 8.2.
+# For a future Debian 13 (Trixie), you would likely change this to "8.3".
+PHP_VERSION="8.2"
