Upgrade from 7.10 to 8.04 problem

[Phil Sexton]

Hi listees,

I have read the upgrade pages and guides I found at 
<http://www.ubuntu.com/> and the update manager reports that I need 
more space in /boot, which puzzles me.  I can't imagine why /boot is 
used rather than the root partition, /.

I have a separate /boot partition and df -h reports (for the 
relevant partitions):
/dev/sda3             9.2G  5.9G  2.9G  68% /
/dev/sda1              74M   34M   36M  49% /boot

Does anyone know how to use / rather than /boot for the upgrade?

I do have the installation CD for 8.04 and a separate /home 
partition, so I could do a complete re-install if I have to, but 
remembering all the programs I need/want is a PITA, so I had rather 
try the upgrade.
