fc9 and rhel5 shared /boot and lvm coexistence

[John Priddy]

So I would like to have rhel5 and fc9 coexisting on the same physical 
disk.  My questions/concerns are as follows:

1.  Is there any issue with sharing the /boot mountpoint/partition 
between both?

2.  I haven't worked a lot with shuffling around VGs, but how about 
sharing lvm volumes in general?  If I create some generic (not root) lvm 
volume and lay down an ext3 filesystem in FC9 should I expect any 
problems when trying to mount the same in RHEL5?  Is there any issue I 
should be aware of regarding differing versions of lvm?  Is it worth 
while/possible to share the swap volume -- lets say I put the computer 
into hibernate in FC9, then later on I boot up into RHEL5, whats the 
worst thats going to happen?

3.  Anyone else out there doing something like this that has any 
additional advice?

Thanks

John
