Customizations
Customizations are blueprint entries that aren't package related.
Customizations are other image specifications that aren't part of package specifications. These other items might include predefined users and groups, SSH keys that implement system security, and other data.
Customizations in blueprints can be varied. A customization that has a general application,
such as specifying a host name for the image, is defined in a
[[customizations]]
block entry. More specific customizations would have
tags appended to the heading to become better identifiers. For example, user definitions are
in a [[customizations.user]]
block, while serviced
customizations are under the [[customizations.services]]
heading, and so
on.
Similar to package listings, customization parameters also follow the
parameter = value
format.
