Description of problem:

In the latest rawhide live iso 04.04

I was unable to install on a 4GB usb stick

Starting with anaconda complaining about not enough disk space
( 4096 minimun ) I press back and anaconda starts to transfer the image to 
to the usb stick???? ( another bug.. )

Then install fails in the middle of the transfer. ( another bug..)

Followed by an option for me to save the error msg which I cant
because clicking "save" crashes the application ( another bug ) 

Then I try again and I choose the partition layout ( custom layout )
no complaints about size this time, Again when transferring the image 
to the usb-stick it fails in middle of the transfer.

Anaconda needs to have a different default partition layout for size
smaller than 4096.

if less than 4096 space on selected hd then do 
boot + needed space for anaconda to install, minust total hd space = swap size

or by setting swap partition to a fixed size, ( 256. 512 or 1024 ).

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