Data directory
==============

Data directory can be located in several locations. There are defaults depending on your OS,
and you can specify a custom its location. Two parts are splitting the data directory: the *root*,
and the *target*.

Alter defaults
--------------

The data directory path is splitted in two parts, the *root* and the *target*. Each are
editable.

root
++++

The root is the base directory where data directories belonging to different installations are
stored. The root is altered by the environment variable **KIWI_ALT_DATADIR** that you
must set.

target
++++++

The target is the datadir of the installation. It is made by the concatenation of
two values in the info.json : **{companyName}/{productName}**. If one of these two
is not in the file, there are no modification.
