A zipl configuration file comprises a default section and one or more sections with IPL configurations. In addition, there can be sections that define menu configurations.

[defaultboot]
a default section that defines what is to be done if the configuration file is called without a section specification.
[<configuration>]
one or more sections that describe IPL configurations.
:<menu_name>
optionally, one or more menu sections that describe menu configurations.

A configuration file section consists of a section identifier and one or more option lines. Option lines are valid only as part of a section. Blank lines are permitted, and lines that begin with the number sign (#) are treated as comments and ignored. Option specifications consist of keyword=value pairs. There can but need not be blanks before and after the equal sign (=) of an option specification.
