      It wouldn't be the first. (see below)

    I came to rawhide from cooker (Mandriva) almost two years ago. 
Mdv's utility (urpmi) displayed disk space needed rather than d/l 
size. Most urpmi complaints on the cooker ML were that d/l size 
should be displayed, not disk space. As when updating, disk space 
change is negligible, but d/l size is much more important.  I used 
40%, eg, if urpmi announced the updates totaled 200MB, the 
approximate d/l would be 80MB's.  On coming to Fedora, one of the 
things I appreciated most was that yum displayed d/l size(s)/total, 
not mostly useless disk space needed. Please keep it that way.
