+
+
+NAME
+----
+cdist-type__mkfs - build a linux file system
+
+
+DESCRIPTION
+-----------
+This cdist type is a wrapper for the mkfs command.
+
+
+REQUIRED PARAMETERS
+-------------------
+type::
+   The filesystem type to use. Same as mkfs -t.
+
+
+OPTIONAL PARAMETERS
+-------------------
+device::
+   defaults to object_id
+
+options::
+   file system-specific options to be passed to the mkfs command
+
+blocks::
+   the number of blocks to be used for the file system
+
+
+EXAMPLES
+--------
+
+--------------------------------------------------------------------------------
+# reiserfs /dev/sda5
+__mkfs /dev/sda5 --type reiserfs
+# same thing with explicit device
+__mkfs whatever --device /dev/sda5 --type reiserfs
+
+# jfs with journal on /dev/sda2
+__mkfs /dev/sda1 --type jfs --options "-j /dev/sda2"
