# Specify installation method to use for installation
# To use a different one comment out the 'url' one below, update
# the selected choice with proper options & un-comment it
#
# Install from an installation tree on a remote server via FTP or HTTP:
# --url         the URL to install from
#
# Example:
#
# url --url=http://192.168.122.1/image
#
# Modify concrete URL in the above example appropriately to reflect the actual
# environment machine is to be installed in
#
# Other possible / supported installation methods:
# * install from the first CD-ROM/DVD drive on the system:
#
# cdrom
#
# * install from a directory of ISO images on a local drive:
#
# harddrive --partition=hdb2 --dir=/tmp/install-tree
#
# * install from provided NFS server:
#
# nfs --server=<hostname> --dir=<directory> [--opts=<nfs options>]
#
# Set language to use during installation and the default language to use on the installed system (required)
lang en_US.UTF-8

# Set system keyboard type / layout (required)
keyboard us

# Configure network information for target system and activate network devices in the installer environment (optional)
# --onboot      enable device at a boot time
# --device      device to be activated and / or configured with the network command
# --bootproto   method to obtain networking configuration for device (default dhcp)
# --noipv6      disable IPv6 on this device
#
# NOTE: Usage of DHCP will fail CCE-27021-5 (DISA FSO RHEL-06-000292). To use static IP configuration,
#       "--bootproto=static" must be used. For example:
# network --bootproto=static --ip=10.0.2.15 --netmask=255.255.255.0 --gateway=10.0.2.254 --nameserver 192.168.2.1,192.168.3.1

# The OpenSCAP installer add-on is used to apply SCAP (Security Content Automation Protocol)
# content - security policies - on the installed system.This add-on has been enabled by default
# since Red Hat Enterprise Linux 7.2. When enabled, the packages necessary to provide this 
# functionality will automatically be installed. However, by default, no policies are enforced,
# meaning that no checks are performed during or after installation unless specifically configured.
#  
#  Important
#   Applying a security policy is not necessary on all systems. This screen should only be used
#   when a specific policy is mandated by your organization rules or government regulations.
#   Unlike most other commands, this add-on does not accept regular options, but uses key-value
#   pairs in the body of the %addon definition instead. These pairs are whitespace-agnostic.
#   Values can be optionally enclosed in single quotes (') or double quotes (").
#   
#  The following keys are recognized by the add-on:
#    content-type - Type of the security content. Possible values are datastream, archive, rpm, and scap-security-guide.
#      - If the content-type is scap-security-guide, the add-on will use content provided by the
#        scap-security-guide package, which is present on the boot media. This means that all other keys except profile will have no effect.
#    content-url - Location of the security content. The content must be accessible using HTTP, HTTPS, or FTP; local storage is currently not supported. A network connection must be available to reach content definitions in a remote location.
#    datastream-id - ID of the data stream referenced in the content-url value. Used only if content-type is datastream.
#    xccdf-id - ID of the benchmark you want to use.
#    xccdf-path - Path to the XCCDF file which should be used; given as a relative path in the archive.
#    profile - ID of the profile to be applied. Use default to apply the default profile.
#    fingerprint - A MD5, SHA1 or SHA2 checksum of the content referenced by content-url.
#    tailoring-path - Path to a tailoring file which should be used, given as a relative path in the archive.
#
#  The following is an example %addon org_fedora_oscap section which uses content from the
#  scap-security-guide on the installation media: 
%addon org_fedora_oscap
        content-type = scap-security-guide
        profile = xccdf_org.ssgproject.content_profile_stig
%end

# Packages selection (%packages section is required)
%packages

# Require @Base
@Base

%end # End of %packages section

# Reboot after the installation is complete (optional)
# --eject       attempt to eject CD or DVD media before rebooting
reboot --eject
