automatic-ubiquity questions

[Richard Feltstykket]

Hi,

I hope this is the right place to ask this question, if not, feel free 
to direct me somwhere else:

I'm trying to preseed a Mint 15 desktop installation for deployment and 
I'm running into some trouble.  It seems the installer ignores some d-i 
statements:

d-i apt-setup/local6/repository string \
        http://apt.puppetlabs.com raring main dependencies
d-i apt-setup/local0/comment string puppetlabs apt
d-i apt-setup/local0/key string http://apt.puppetlabs.com/pubkey.gpg
d-i pkgsel/include string openssh-server puppet

I don't see any message about them in the logs, even with 
debug-ubiquity.  I've confirmed from a shell while the installer is 
going that the system is up on the network and able to access the 
repository.  It is reading d-i statemnts (such as automatic user 
account/password creation), so I'm sure the file is being read. 
Additionally, these d-i statements works fine in the Debian installer, 
as I use them for Ubuntu.   Mint only uses Ubiquity installer however.

Is there a list of all Ubiquity specific options anywhere I can review?

Thanks,
Richard
