This is a quick introduction to AII configuration. AII is Quattor component in charge of producing Kickstart configuration file used for initial installation.

Configuration specific to initial installation is made of 2 parts :
 * AII_xxx variables used to configure base environment (keyboard, language...). This works both for v1 and v2.
 * Filesystems and block devices definitions : this is specific to AII v2.
 
== AII Variables ==


== File Systems and Block Devices ==

In AII v2, block devices and file systems are declared separatly. 

=== File Systems ===

Filesystems are declared as an ordered list allowing to customize different aspect of a file system (mount point, mount options, format, ...). Each file system in the list is described as a nlist. One property in the nlist describing a file system is `block device` : its value is an entry in the structure describing block devices (physical disk, logical volumes, ...). To add or modify a filesystem on a system, it is recommended to use 'fileystem_mod` function. An example is :

{{{
"/system/filesystems" = filesystem_mod(
  list(nlist ("block_device", "partitions/" + DISK_PART_BOOT,
              "mountpoint", "/boot",
              "format", true,
              "mount", true,
              "preserve", false,
              "type","ext2"),
       nlist ("block_device", "partitions/" + DISK_PART_SWAP,
              "format", true,
              "mount", true,
              "preserve", false,
              "type","swap",
              "mountpoint","swap"),
       nlist ("block_device", "partitions/" + DISK_PART_ROOT,
              "format", true,
              "preserve", false,
              "mount", true,
              "type","ext3",
              "mountpoint","/"),
       nlist ("block_device", "logical_volumes/usrvol",
              "format", true,
              "preserve", false,
              "mount", true,
              "type","ext3",
              "mountpoint","/usr"),
);
}}}
