  zypp does not do this automatically, but the application is able to 
  check how much space the selected packages will consume. But this 
  requires that the repositories provide proper disk usage data (susetags 
  does, yum does not). In case we ship .solv files for 11.0 they hopefully 
  do include disk usage data.


But rpm checks as well. In order to see how the package distributes 
across filesystems rpm has to analyse the packages filelist, and they do 
not take hardlinks into account.

If you sum up the filesizes

        $ rpm -q glibc-locale -lv | awk '{s+=$5}END{print s}
        300748755

you get ~300MB.

But a lot of these files are hardlinks, thus the actual size is 

        $ rpm -q glibc-locale -i | grep '^Size'
        Size        : 76262588  

~76MB.


AFAIK rpm stores device and inode data, so it should be possible to 
detect the hardlinks and compute it correctly.
