Ok I see what you mean, but I still do not understand how I can prompt the user for a kickstart file path, store their input in a variable, and then reference said variable when I pass the ks= kernel commandline option. I understand how the PXE menu works, but the problem is that our menu file is growing rapidly as we add distros, and I have been asked specifically to get it down to one default entry. If there is a way to reference the user's input (other than by using a label) then this can be easily accomplished. I do not think this is possible to do at this point, however.

tk::menu::item
Menu::Item(3pm) User Contributed Perl Documentation Menu::Item(3pm)
NAME
Tk::Menu::Item - Base class for Menu items
SYNOPSIS
require Tk::Menu::Item;
my $but = $menu->Button(...);
$but->configure(...);
my $what = $but->cget();
package Whatever;
require Tk::Menu::Item;
@ISA = qw(Tk::Menu::Item);
sub PreInit
{
my ($class,$menu,$info) = @_;
$info->{'-xxxxx'} = ...
my $y = delete $info->{'-yyyy'};
}
DESCRIPTION
Tk::Menu::Item is the base class from which Tk::Menu::Button, Tk::Menu::Cascade, Tk::Menu::Radiobutton and Tk::Menu::Checkbutton are
derived. There is also a Tk::Menu::Separator.
Constructors are declared so that $menu->Button(...) etc. do what you would expect.
The "-label" option is pre-processed allowing ~ to be prefixed to the character to derive a "-underline" value. Thus
$menu->Button(-label => 'Goto ~Home',...)
is equivalent to
$menu->Button(-label => 'Goto Home', -underline => 6, ...)
The "Cascade" menu item creates a sub-menu and accepts these options:
-menuitems
A list of items for the sub-menu. Within this list (which is also accepted by Menu and Menubutton) the first two elements of each item
should be the "constructor" name and the label:
-menuitems => [
[Button => '~Quit', -command => [destroy => $mw]],
[Checkbutton => '~Oil', -variable => $oil],
]
-postcommand
A callback to be invoked before posting the menu.
-tearoff
Specifies whether sub-menu can be torn-off or not.
-menuvar
Scalar reference that will be set to the newly-created sub-menu.
The returned object is currently a blessed reference to an array of two items: the containing Menu and the 'label'. Methods "configure"
and "cget" are mapped onto underlying "entryconfigure" and "entrycget".
The main purpose of the OO interface is to allow derived item classes to be defined which pre-set the options used to create a more basic
item.
BUGS
This OO interface is very new. Using the label as the "key" is a problem for separaror items which don't have one. The alternative would be
to use an index into the menu but that is a problem if items are deleted (or inserted other than at the end).
There should probably be a PostInit entry point too, or a more widget like defered 'configure'.
