Hi there,

I am working on a fedora remix.
I need to let user to add organization name/id during the user account creation.
Do you mean setting the gecos field for the user ?[0]

Some what this is I am expecting but I don't need it to keep in  /etc/passwd (save it in different file is good enough) as multiple users in the same system should have same id (centerid).

Then you shouldn't need to involve anaconda.
we should able to retrieve the given id during the installation if we remove all local users. Imagine a situation only root account exists. Best solution is to write that value to a different file such as /etc/centerid or /etc/service, etc

Currently this is not supported in the graphicala and text user interface, but can be done
via kickstart (which is basically a config file that can be used to configure an installation)[1].
A kickstart file can be loaded either from network or from local media during the installation.

Isn't it a static value if we use kickstart ?

Depends on your definition of "it"...
normally we hardcode values for variables in the kickstart right?  
I thought you were asking to hardcode centerid in kicksart.
Can we prompt user to input a value during the installation using kickstart?

Anaconda will prompt for any required information that has not been provided already, but anaconda only *requires* what is needed to perform the install. 
 you mean only for what anaconda usually require but it wont support on additional requirements define in kickstart, am I right?

I also thinking about a silent installation (unattended).
It would be great if its possible to prompt via kickstart but I never heard such option.

Unattended install is kickstart's bread and butter.[2]
It sounds like you would be better off putting these customisation(s) into the %post script  of the kickstart file.
You might have the grub menu contain a list of the hundreds of servers, the human installer chooses one and that determines the kickstart file, and thus the custom parts.
let people to select a centerid from a list with hundreds of items not practicle at least it cause human errors of selecting wrong centerid.

Or, depending on what you know about, hardware, on-site networking, etc. the %post script might be made smart in a what-machine-am-I kind of way, then have it do the custom parts automagically...
Or, some other creative way to utilize grub2, kickstart, and so on.

what we know is there is a lab with 1 server, 20 machines (at least) and everything networked with dhcp enabled ADSL/4G router.
But there is no installation server setup only installation mechanism is DVD rom.


If what you need is really setting the gecos field manually in the user interface during the installation,
it looks like we could add it to the "Advanced" dialog on the user configuration screen.

this would be great if if you can enable it.
Is there any guide or examples on such additional changes for anaconda?
