Including my private reply for the benefit of the list.

I don't understand this statement. Why not?

netboot supports preseed/url, i.e. network preseeding; this is
documented here:


You don't have to burn a CD.

(netcfg/choose_interface is read before the network preseed file,
though, for obvious reasons, so it still needs to go on the kernel
command line.)

I disagree, since it's not a top-level argument in the same sense as
everything else there; the language/country preseed arguments aren't
documented there either. That section would get unreadably long if every
possible debconf question were documented there.

It should be documented a little more clearly in
though (and the language/country configuration there should be updated
to be just "preseed/locale=en_US"). Fixed in my local tree, so no need
to file a bug.

That, and you can only use a maximum of 32 command line options and 32
environment options. (This was lifted from 8 in earlier kernel versions.
I've just changed the manual to mention the newer raised limit.)

Try replacing "languagechooser/language-name=English
countrychooser/shortlist=US" with "preseed/locale=en_US".
