Customized Distribution

["Ali Majdzadeh" <ali majdzadeh gmail com>]

Hello All
Following the instructions mentioned at the following address:
http://fedoraproject.org/wiki/Anaconda/Customization
I am trying to build a custom distribution based on CentOs 5.01.
I have performed the following steps:
$ mount /dev/cdrom /mnt
$ mkdir ~/mydistro
$ cp -avp /mnt/* ~/mydistro
$ mv ~/mydistro/CentOS ~/mydistro/mydistro
$ cp /mnt/.discinfo ~/mydistro
$ createrepo -g ~/mydistro/repodata/comps.xml ~/mydistro/mydistro
$ mkdir -p ~/mydistro/mydistro/base
$ cp -avp ~/mydistro/repodata/* ~/mydistro/mydistro/base
$ buildinstall --version 2 --product "MyDistro" --release "MyDistro Linux" --prodpath mydistro ~/mydistro
$ rm -Rf ~/mydistro/.olddata
$ pkgorder ~/mydistro i386 mydistro | tee ~/mydistro/pkgfile
In the last step, i get the following error:
kernel-xen-2.6.18-53.el5.i686.rpm
kernel-PAE-devel-2.6.18-53.el5.i686.rpm
kernel-debug-devel-2.6.18-53.el5.i686.rpm

yum.Errors.RepoError: failure: CentOS/kudzu-1.2.57.1.15-1.el5.centos.i386.rpm from anaconda: [Errno 256] No more mirrors to try.

Any ideas? Why does it try to check the yum mirrors? Is there anyway to perform the operation locally?
Thanks in advance.

Kind Regards
