Selective install using apt-method in dselect

[Kent West]

I've got 200+ MB of files selected in dselect for
download/installation, and I'm using the apt method. dselect
tells me that my /var/[something] doesn't have enough space free
and aborts. IIRC, the ftp method in such a situation allowed you
to do a selective install at that point; am I missing something
or is the apt method missing this feature?
