Description of problem:
Attempting to update FC4 box (box specs 512 Mb of RAM, 919M of Swap, 180Gb 
disk) from a DVD.
Everything was proceding normal, the previous installaton of FC4 was found and 
selected to be updated.  While preparing the transaction, after a few minutes 
a window appeared and claimed it failed due to being out of disk space. There 
are more than 150Gb free on the physical disk as reported by df -h.  If its a 
disk its referring to, it must be a ram disk.  The physical disk was unchanged 
after this, so FC4 still works.   The popup also said it should let the user 
go back and try again, but I guess that feature hadn't been implemented,so the 
install just exited.

If 512Mb of ram isn't enought to run anaconda/yum for fc5, then I guess this 
isn't a bug.  But I don't know how I'll get updated if thats the case.
I will say that I have a bunch of software installed.  Both Gnome, and KDE, 
and Open Office and much more using yum.

Version-Release number of selected component (if applicable):

FC5 test 3
How reproducible:
I didn't try to reproduce.

Steps to Reproduce:
1.
2.
3.
  
Actual results:
Upgrade failed due to out of disk space updating computer with modest amount 
of ram by todays standards, and lots of fc4 packages installed on it.

Expected results:
Ugrade to succeed. 
Additional info:
 Maybe yum should do smaller transactions by groups, such as base first, then 
X11...,  my impression was it tried the whole thing as one huge transaction.  
I guess I can make a local repo out of my DVD, and then do an iterative update 
of the packages for myself.
