You can get dselect to find the files for you.

Just as well.

You must do exactly what I said: copy only the first word of the
Status field of each package's entry, and replace the first word of
the corresponding entry on the other system.  The first word is the
`desired state' as set by dselect's selection interface and used by
the [I]nstall option.

If there isn't an entry for a package you want then make one like
  Package: whatever
  Status: install ok not-installed
