CentOS - Aug 2016 - Centos7 kickstart & pxe

Hello All, 

I'm trying to get kickstart to work through pxe. 
So far I've set up dhcp server, tftp and so on. 
But it seems at some point I always get stuck because the iso file is
write-protected.

I've tried remounting it rw, and I 've dd the iso first, I then get EM
not a block device.

Any help would be appreciated. 

Greetings, J.

I'd always tend to just expose the install image via HTTP.

Hello John,

thanks for the reply.
I found a useful tutorial on kickstart/http here:
http://www.tomsitpro.com/articles/kickstart-linux-automation,2-798.html
but if I understand it right, via http is not an unattended install. You have to
have a boot medium.

If I'm correct people do unattended installs all the time, so I don't
understand why all the tutorials I try fail on the same point.
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.

Greetings, J.
