Interactive PXE Boot Menu

I have been asked to modify our PXE server such that there will be only one entry in the pxelinux.cfg/default file, where the same kernel and initrd.img will be used regardless of what operating system is to be installed, and the user will type in the path to the kickstart file that will be used. I have attempted to complete this task by using a modular kickstart, and asking for user input in the %pre section, which failed miserably. I have also looked into the possibility of getting user input from the PXE boot menu. Is it somehow possible to refer back to the user input when using prompt 1....label? Can this information be referenced other than by using label? Is there a better way to accomplish this?

Unfortunately, installing extra packages or tools on our pxe server is not an option.

KSVALIDATOR(1)						      General Commands Manual						    KSVALIDATOR(1)

NAME
ksvalidator -- verify the syntax of a kickstart file SYNOPSIS
ksvalidator [-e | --firsterror] [-i | --followincludes] [-l | --listversions] [-v | --version VERSION] INFILE DESCRIPTION
ksvalidator is a program that takes an input kickstart file and attempts to verify that it is syntactically correct. This includes check- ing basics like proper quoting and making sure required options have values, and more advanced checks like verifying the file does not include deprecated or removed kickstart commands. Mutually exclusive options can also be caught, as can certain classes of partitioning errors (like using the same device name multiple times). ksvalidator does have its limitations. It cannot run validate the syntax of %pre and %post scripts, nor does it attempt to run them. It cannot check that the %packages section is valid. Most importantly, it cannot guarantee that an input kickstart file will install prop- erly, because it does not understand the complexities of partitioning and what potentially already exists on disk. EXIT STATUS
ksvalidator returns 0 on success, and 1 if INFILE does not exist or there is an error parsing the kickstart file. OPTIONS
-e, --firsterror Stop on the first warning or error. By default, ksvalidator will attempt to process the entire file, potentially raising multi- ple errors. -i, --followincludes Process included files in the input file when they are seen, like anaconda would. If the included file does not exist (this can happen for a variety of reasons, but the most common being a %pre script that generates an included file) and this option is given, an error will be generated and processing halted. -l, --listversions List all versions of kickstart syntax supported by ksvalidator. This is useful for determining what values can be fed back in on a second run. -v, --version VERSION Use this version of kickstart syntax when processing the file, or the latest if no version is given.
