Regarding splittree.py error

[Nitesh jain <jainitesh@xxxxxxxxx>]

Hi ,
  Im running the procedure converting the extracted CentOS 4.4 ISO image, back to ISO image. Im btween my procedure i caught an error pls help me out it is very urgent to me and thanks in advance.

The details are as follows:- 

My centOS version is 4.4.

STEP 1: Once the ISO files are downloaded, i need to extract their contents into our working directory, with the following commands. (You should place these into a script and execute it.)

#!/bin/bash

for iso in CentOS-4.4-i386-bin1of4.iso CentOS-4.4-i386-bin2of4.iso CentOS-4.4-i386-bin3of4.iso CentOS-4.4-i386-bin4of4.iso; do

mount -o loop $BUILDBASE/linux/$iso /mnt ; cd /mnt ; \
tar -cf - * | ( cd $BUILDBASE/linux/i386/ ; tar -xpf - ) ; \
cd $BUILDBASE ; umount /mnt

done

STEP2: I have edited my required file in extracted image.

STEP3:

First, we need to re-generate the hdlist file. Do so with the following command:

genhdlist $BUILDBASE/linux/i386

Next, create our package order file by issuing the following command:

pkgorder $BUILDBASE/linux/i386 i386 | tee $BUILDBASE/linux/pkgfile.`date +%Y-%m-%d`

Now, update the installation files by entering the following command:

buildinstall --comp dist-4.4 --pkgorder $BUILDBASE/linux/pkgfile.`date +%Y-%m-%d` \
--version 4.4 --product 'CentOS' --release 'CentOS 4.4 \
$BUILDBASE/linux/i386

All the above procedure went successfully except a lot of warnings i think tat warnings are og no use. :)

STEP4:The following commands will do the split and re-create the hdlist files for each CD:
        
          

RELEASE="CentOS 4.4 with updates to $(date '+%Y-%M-%d %H:%m')"
            
            rm -rf $BUILDBASE/linux/i386-disc[1-8]
            

Now after this a caught my problem:-

splittree.py --arch=i386 --total-discs=4 --bin-discs=1 --src-discs=3 --release-string="$RELEASE" \
            --pkgorderfile=$BUILDBASE/linux/pkgfile.`date +%Y-%m-%d` \
            --distdir=$BUILDBASE/linux/i386 \
            --srcdir=$BUILDBASE/linux/i386/SRPMS --productpath=CentOS

and the error is 

Traceback (most recent call last):
  File "/usr/lib/anaconda-runtime/splittree.py", line 455, in ?
    logfile = timber.main()
  File "/usr/lib/anaconda-runtime/splittree.py", line 380, in main

  File "/usr/lib/anaconda-runtime/splittree.py", line 39, in nvra
