FWIW I get better results using a RedHat-style Kickstart file, with ks=http://blah, instead of a preseed file.
But analogously, I cannot seem to defeat the prompt about over-writing an existing LVM configuration.
Therefore I theorise this is not a problem with the pressed parser and kickstart parser separately, but is instead a problem with the honouring of the parsed directives, after the parse step is done and the difference between preseed and kickstart is irrelevant.
