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. 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"),
);
