+sysctl
+======
+
+This formula ensures that a sysctl parameter is present on the system
+from a pillar file.
+
+
+Here's a small pillar data sample::
+
+    sysclt:
+      lookup:
+        pkg: procps-ng
+        config_location: /etc/sysctl.d
+      params:
+        vm.swappines: 
+          value: 20
+          config: 10-swap.conf
+        fs.file-max: 10000
+
+
+The state sysclt will ensure these are present on the system
+based on the sysctl module of salt. 
+
+if no config value is given the key value will be written based host system.
+on systemd systems this will be /etc/sysctl.d/99-salt.conf
+on sysv init systems it will be /etc/sysctl.conf
+
