%pre and include files

[Shabazian, Chip]

Here, just fix your HD determining problem.  This is what I do in my
%pre:

# Determine how many drives we have
set $(list-harddrives)
let numd=$#/2
d1=$1
d2=$3

# This is the LD&E scheme for two or more drives

if [ $numd -ge 2 ] ; then
cat << EOF >> /tmp/partinfo
2 + Drive Partitioning info
EOF

else
cat << EOF >> /tmp/partinfo 
1 Drive Partitioning info
EOF

Then in the top command section, use: 
%include /tmp/partinfo

As for debugging in %pre, I put a sleep 999999999 in the pre, then
simply work at the console.  There are other ways as well, but this
works for me.  When you want to move past the sleep, just kill the
process.  Doing this, you can step through your pre or post with sleeps
at any point you want.

Subject: %pre and include files

I have a pretty nice kickstart setup going but now I need two different
LVM/RAID schemes: One for our 2 drive systems which we want mirrored and
one for our 4 drive systems which we want configured with a RAID 5 and a
spare. So I split out the common kickstart configs into a file called
ks-standardoptions.cfg so I have one central place to edit the things in
common and have only the machine specific LVM/RAID config and an include
in each main kickstart config. Eventually I will try to put some smarts
in the %pre to detect how many HD's the machine has and load the right
one. For now I choose at boot time. The problem is: The machine only
tftp's the main kickstart file. How do I get the other file to be
included? Googling reveals that most people seem to put a wget in a %pre
and then include the file they wget. I have tried that but it seems
either it is not successfully retrieving the config file to be included
or it is not being included at all.

I do not see any way to debug what happens during %pre as I do not see
any output, not even errors.  Is there some option I am missing? Some
way to single step it? I guess I could try making the shell /bin/sh -x
and see if it echos the commands to the screen as they execute.

Does it matter where the %pre and %post sections are located in the
kickstart config? Most people seem to put them at the end. But my
%include is at the beginning. I read somewhere that two passes are made
processing includes so that if the file to be included is not present
the first time around it eventually executes the %pre and it tries
again. Is that correct?

An example of my main config can be found here:

Anyone see a problem with this? Thanks!
