Installation guide
This section must be at the end of the kickstart file (after the commands) and must start with the
%pre command. You can access the network in the %pre section; however, name service has not
been configured at this point, so only IP addresses work.
Note
Note that the pre-install script is not run in the change root environment.
--interpreter /usr/bin/python
Allows you to specify a different scripting language, such as Python. Replace /
usr/bin/python with the scripting language of your choice.
6.1. Example
Here is an example %pre section:
%pre
#!/bin/sh
hds=""
mymedia=""
for file in /proc/ide/h* do
mymedia=`cat $file/media`
if [ $mymedia == "disk" ] ; then
hds="$hds `basename $file`"
fi
done
set $hds
numhd=`echo $#`
drive1=`echo $hds | cut -d' ' -f1`
drive2=`echo $hds | cut -d' ' -f2`
#Write out partition scheme based on whether there are 1 or 2 hard drives
if [ $numhd == "2" ] ; then
#2 drives
echo "#partitioning scheme generated in %pre for 2 drives" > /tmp/part-include
echo "clearpart --all" >> /tmp/part-include
echo "part /boot --fstype ext3 --size 75 --ondisk hda" >> /tmp/part-include
echo "part / --fstype ext3 --size 1 --grow --ondisk hda" >> /tmp/part-include
echo "part swap --recommended --ondisk $drive1" >> /tmp/part-include
echo "part /home --fstype ext3 --size 1 --grow --ondisk hdb" >> /tmp/part-include
else
#1 drive
echo "#partitioning scheme generated in %pre for 1 drive" > /tmp/part-include
echo "clearpart --all" >> /tmp/part-include
echo "part /boot --fstype ext3 --size 75" >> /tmp/part-includ
echo "part swap --recommended" >> /tmp/part-include
echo "part / --fstype ext3 --size 2048" >> /tmp/part-include
echo "part /home --fstype ext3 --size 2048 --grow" >> /tmp/part-include
fi
This script determines the number of hard drives in the system and writes a text file with a differ-
ent partitioning scheme depending on whether it has one or two drives. Instead of having a set
of partitioning commands in the kickstart file, include the line:
%include /tmp/part-include
The partitioning commands selected in the script are used.
