sharing /boot beween FC1 and FC2

[Chris Jones <jonesc hep phy cam ac uk>]

Hi,

I want to upgrade my system to FC2, but since it took a long time to get 
things going correctly in FC1 I want to dual boot both for a while 
instead of upgrading only to discover things don't work, sharing /home 
and a few data partitions. I already have a /boot partition for FC1 and 
I am wondering if I can just point the FC2 install to this during 
installation - will it add itself correctly to grub.conf, or will it 
crash my FC1 boot options ? Is this just a bad idea ?

cheers Chris
