# 
# This is where you specify the partitions to be used in the install.
# There are several sections that we'll cover in order.
# 
# If you are doing a kickstart install on a new drive, the partition table
# will likely corrupt.  The zerombr command can be used to clear the
# partition table if it is corrupt; otherwise it will take no action.  In
# order to clear the partition table, follow the zerombr command with
# "yes"; if followed by "no", no action will be taken.
#
# Example:
#zerombr yes
#
# The clearpart command is used to control which partitions are to be wiped
# from all drives.  Follow the clearpart command with "--all" to remove all
# partitions from all drives, or "--linux" to remove all Linux-related
# partitions (ie., partitions of type "Linux native" and "Linux swap") from
# all drives.
#
# Example:
#clearpart --linux
# 
# Next, specify the partitions that you'd like to create.  Partitions are
# only created from free space available on the system.  Enter one
# partition per line using the following format:
#
# part <mntpt> --size <size in megs> [--grow] [--maxsize <size in megs>]
#
# Where <mntpt> is the desired mount point for the partition (or "swap" for
# swap partitions).  Add "--grow" to create a partition that will grow to
# fill all remaining space on the drive.  To limit the affect of --grow,
# you can add "--maxsize" followed by a size specification.
# 
# Examples:
#part / --size 250
#part swap --size 32
#part /usr --size 500 --grow --maxsize 800
#part /tmp --size 100 --grow
