# In this OS profile, data is largely filled in during the %pre
# phase, rather than the kickstart actually having the content.
# None of the files shall be replaced during an upgrade in
# /var/lib/confluent/public/os/<profile>, so customization should
# be done by modifying files in /var/lib/confluent/public/os/<profile>

# /tmp/rootpw will provide a 'rootpw' line, either locking password if not configured
# or the crypted form.
%include /tmp/rootpw

# timezone is fetched from confluent server, which provides the
# timezone that the management server itself is in by default.
%include /tmp/timezone

# similar to timezone, confluent is asked to provide the
# deployment servers language info and replicate that
# to the deployment target.
%include /tmp/langinfo

# bootloader may be specified if crypted.grubpassword is set on
# a node. This will become a bootloader line if a password
# was specified
%include /tmp/grubpw

# The default partition scheme is applied to a single drive, using
# the getinstalldisk script to make a best guess as to the most
# appropriate device. See pre.sh and getinstalldisk to customize
# the automatic behavior, or comment out/delete the 
# following line and provide your own manual partition plan
# instead
