1st disk only automated install

[Broekman, Maarten]

Phil,
	In the %pre section of your kickstart script, you can check to
see if there is data in various /proc files (/proc/partitions or
/proc/diskstats for example) and based on the device entries there, set
up the drive partitions...

# cat /proc/partitions
major minor  #blocks  name

 104     0   35561280 cciss/c0d0
...
 104    16  143367120 cciss/c0d1
...
 104    32   35561280 cciss/c0d2
...

Like Kris, I have an HP hardware RAID controller in the way, but you
should see your pata/sata/ide drives in here as well.  Based on that you
can write out a file during the %pre and then %include it for your disk
partitioning.

I have the following line in my ks.cfg:

%include /tmp/disk_map


Then in the %pre section, I check for the disk driver module (cciss,
BusLogic, mptscsi) and the size of the disk before writing
/tmp/disk_map.

if   lsmod | grep ^cciss    ; then
	# Check sizes
	if size1 then
		DRIVE_TYPE="a"
	elif size2 then
		DRIVE_TYPE="b"
	...
	fi
elif lsmod | grep ^BusLogic ; then
	DRIVE_TYPE="n"
elif lsmod | grep ^mptscsi ; then
	DRIVE_TYPE="z"
fi

case DRIVE_TYPE in
         "a")
            cat > /tmp/disk_map <<EOF
part /boot --fstype ext3 --size 100  --asprimary --ondisk cciss/c0d0
part swap  --fstype swap --size $SWAP --asprimary --ondisk cciss/c0d0
part /     --fstype ext3 --size 3072             --ondisk cciss/c0d0
part /var  --fstype ext3 --size 3072             --ondisk cciss/c0d0
part /tmp  --fstype ext3 --size 2048             --ondisk cciss/c0d0
part /opt  --fstype ext3 --size 4096 --grow      --ondisk cciss/c0d0
EOF
         ;;
	...

Thanks Kris for your reply.  This would work on a case by case basis.  
However, what I am looking for is a generic setting so that one
kickstart 
file can be indiscriminately used against all of my machines.  

And this is what I am not sure how to do.

Thank you,

Phil
