When anaconda sees partitioning configuration stanzas in the kickstart
file, it takes them on unconditionally. Is there a way to give the
user a chance to override them during installation?

A search over the kickstart doco does not show any useful hints, and
the GUI kickstart configurator doesn't offer any options that seem
suitable. Perhaps there is a smart way to do this that I'm not aware
of? How do liveCDs say "ah, if you let me, I'll autopartition it like
this *whack!*, but if you want to do it yourself, here, have at parted
my friend"?

cheers,



martin

If you remove the configuration options from your kickstart file,
anaconda will stop and ask the user for input, isn't this what you want?

Otherwise create 2 kickstart files on the DVD and chose which one you
use depending on the situation, an easy way of doing that is to edit the
isolinux/isolinux.cfg file on the DVD, with ISO Master for example.

In kickstart it is simple ask the user in %pre, generate the file stanza based on user request, and %include in kickstart the generate file stanza

How does one ask the user in %pre?
