Oh yes, I see ..

I think this not a point.
dinstall get the size.gz file from the .deb file (ar -x) and put it to the
cache area. I don't see the difference?
(And for old .deb files: dinstall unpack the .deb file in /tmp/../ and make
the size.gz-file)

You use .deb file only at install time. After that you will remove all *.deb
from your hard disk. (If you don't remove the *.deb then you have a very big
disk and the kBytes are not the point..)

All the time. You use .deb only for the install time.? You don't?

This is a point. But I say:

see the 'or'

Then put the du information not in the control file but put it in the .deb
file. Make the du-data in a file (size.gz) and put it in the .deb file like
data.tar.gz, control.tar.gz.


You need the information when you install a package on your debian system.
I think it is a nice to download only one file to install the package. I
get often packages with ftp from a mirror and install the packages with:
dpkg -i *.deb. If the the size information isn't in the debian-package, then i
must download two files (NAME-VERSION.deb and NAME-VERSION.size.gz) or dpkg
has no information of the size and can not make a warning message. :-(

We have seperate package-functions and the interface. This is a very good.
You can install package with:
  dpkg
  dselect (with use dpkg)
  apt (with use also dpkg)
The du-information is a information like name, version, depends etc. 
The right place is the .deb-file.
