how to save the kickstart configurator file?
 

I've made a LAN with a PC and a laptop, which are connected through a router. I've setup a web server on the PC and i want to upgrade my Laptop Fedora 2.90 installation with the help of the rpm in my PC.
I found out that i can change my source of installation from Kickstart. However, changes made in Kickstart can only be saved through a complicated procedure ( at least i am not able to understand it). You have to save changes in a file and then somehow load the file. But i can't understand how i can do it. Here's the directions given in
''file:///usr/share/doc/system-config-kickstart-2.5.12/system-config-kickstart-savefile.html''
----------------------------------------------------------------------------------------------------------------------
To save the kickstart file without previewing it, select File => Save File or press [Ctrl]-[S]. A dialog box appears. Select where to save the file.

After saving the file, create a boot diskette from boot.img for CD-ROM installations or bootnet.img for network installations. Copy the kickstart file (ks.cfg) on the boot diskette. Boot from the diskette and type linux ks=floppy to start the kickstart installation.
---------------------------------------------------------------------------------------------------------------------
Boot.img is the one i had written in a cd in order to start my ftp Fedora 2.90 installation (i think), but how to i create one?
What is bootnet.img and how do i create one?
''Copy the kickstart file (ks.cfg)'' anywhere on the boot diskette?


Thanks
