IIRC currently the detailed diskusage (per directory) is only supported 
for the susetags format (i.e. the install repositories), not for the rpmmd 
(XML based) repositories.  There is work underway in current SVN to 
support also diskusage for the XML repositories (e.g. the update repo and 
all buildservice repos are of that type), but I'm not sure how complete 
that is.

But for one solv file either _all_ packages should have that attribute or 
none should have it.  Otherwise that would be a bug.

It's not totally useless IMHO.  Even in the absense of the diskusage 
attribute you still can know the overall installsize (you just don't know 
where exactly that space will be used).  You could for instance attribute 
the whole installsize to the partition that holds /usr .  Not ideal of 
course, but still something.

(but yes, in the future, eventually, all packages will have a diskusage 
attribute).


Ciao,
Michael.
