Hi all,
Probably a simple question, but, I'd like to merge both install DVDs into one directory on my PXE server. Obviously I will need to copy all of the files, but do I need to cast a magical incantation to recreate .discinfo, .treeinfo, etc?
Thanks!

If all you want to do is create a PXE server that can be used to install using NFS, you just need the DVD (or CD) .iso files in some NFS exported (read-only!) directory. Loopback mount the first DVD/CD and copy the image froms from images/pxeboot to /tftpboot and put entries in /tftpboot/pxelinux.cfg/default, and the right 'magic' in /etc/dhcpd.conf and you are good to go.
Thanks!

the .iso files on the nfs ? I thought you put all the files IN the iso
personally, when I do PXE, I use a http style install off a local copy of the repository. Its been a little while since i set it up, but IIRC, there's some mojo you put in the kickstart file on the tftproot to tell it what install type you want (nfs vs http vs whatever)

Ya, I use it over http as well.
In kickstart; use: url --url=http://192.168.1.254/c5/x86_64/img/
In the PXE config file, the matching entry would be something like:
LABEL c5_an-node01 MENU LABEL ^1) Install AN!Node01; Storage Node 01 - Cluster 2 KERNEL boot/c5/x86_64/vmlinuz APPEND initrd=boot/c5/x86_64/initrd.img ks=http://192.168.1.254/c5/x86_64/ks/an-node01.ks ksdevice=eth1
why don't you simply rsync down what you need? Installing of a mounted iso via pxe is probably the less preferred method. rsync also gives you the option of excluding stuff you don't need.

That's what the OP is saying to do when he states you loopback mount the ISO's.

The installer has always known how to deal directly with all the CD iso images under an nfs directory by itself without fiddling with any files. I'd expect it to do the same with the dvds, but haven't tried that since there were two of them.

Just the ISO files themselves in an NFS exported directory, nothing more. Anaconda knows all about mount ... -o loop ... and does what it needs to do. No additional fussing about (no need to install httpd or ftpd, etc.). You just need to install tftpd and dhcpd and there you are.
*Actually* I have also done things like 'install' the pxe boot files in the /boot directory of the target machine and boot it with lilo (grub would also work, but I have always used lilo). This is how I have done clean install upgrades (major version updates -- V3.x => 4.x, or 4.x to 5.x, etc.), with either the ISOs on a separate partition that I was not going to reformat) (eg /home) or on another machine via NFS.

I've done that (well, minus NFS). I can easily enough install without the second DVD ISO, as the servers won't have openoffice anyway.
My question was more a point of curiosity. I supposed I could have said "how can I merge the two ISOs into one" and gotten matching answers. So then, the real question is; How can I recreate the package list that is found in the ISO that anaconda uses to know what packages are available?
Cheers!
