what the --*-selections options do is tell the debian
packaging gremlins to save and recall the list of
packages you want.
when you use dselect (the slink debian way) it does
basically this kind of 'these packages are to be installed
because the boss says so, and these are to be removed, for
the same reason.'
you could do
dpkg -i some-package-name.here.etc.deb
to install each (any) particular package. i'd bet that when you
use the old dselect to do the [I]nstall portion, it'd tell dpkg
to do just that (and more, probably).
but with apt-get these days, you don't have to worry about
directly chatting with dpkg; once your selections are set,
and your sources.list is alright (use apt-setup for that)
just
apt-get update && and-get upgrade
and you're off to the races. right?
unless i'm wrong about all this, which means you'll have to
learn about it on your own. or at least double-check my say-so.
