| Hello John,
|
| thanks for the reply.

|
| If I'm correct people do unattended installs all the time, so I don't

| I must be doing something wrong.
|
| What I did on my last try was:
|
| Download Centos dvd to /tmp
| mount -o loop /path/to/centos-dvd.iso /mnt
| rsync -azvp /mnt/* /var/ftp/pub/
|
| But subsequently I can't change anything in /var/ftp/pub because of read-only
| file system.

Basically in order to boot from the network you need the contents of os/$arch/images/pxeboot/ for your system architecture. You can then use kickstart to point to a media you want to use for the actual installation. This can be that of cdrom, url, nfs, etc. You pass the kickstart parameter to your client using the 'ks=' parameter. the installation media can be from a local rsync of the CentOS repository (to save money) or to a mirror of your choice that may be local to you. Feel free to ask any questions.

Powering Engagement Through Technology
Hello All,
although this post is a few weeks old;
following the advise to use http and to use the ks= parameter, I was able to set this up.
So with the help of some volunteers we set up a Centos-install-fest here at work and
installed some 30 laptops in an hour.
(More would have been possible, the limited factor was the number of Internet cables I could muster.)
So many thanks.
Greetings, J.
