thanks for this, you were right on the money!  taking out the split
lines helped a lot.  

While I have you folks on the line...  

I wonder if there's full documentation somewhere about how one finds out
the options for a d-i preseed variable.  For instance, in my preseed I
have the line:  
d-i  netcfg/choose_interface            select auto
... but actually the network in our classroom is unreliable, and for
truly automatic installation I would prefer to use the "Do not configure
the network atthis time" option.  Should I then replace the above line
with :

d-i  netcfg/choose_interface            select Do not configure the
network at this time
[unwrapped obviously; using evolution here and can't seem to tell it not
to wrap this line...]

If so, is there some way to find out the relevant options in advance
(without just going through an install and noting all the options)

And second, some of the old disks we're installing onto are already
partitioned, and the partition manager stalls on them when attempting
auto-install.  Is there a way to set the (incredibly dangerous) option
of "wipe this Disk and replace with my partitions"?  again, there's
probably some easy way to figure these options out but I don't know

Thanks again!
