[Lancaster] 'Sharing' a /boot Partition - Possible?

[Dave Smith]

Evening again folks.

Another bordering-on-dumb question here I fear.

Two Linux / Unix OS's. One hard drive. What happens if you make them 
both mount the same /boot partition to store their grub config in?

I'm sure I remember Ken mentioning something in this area fairly 
recently when he was talking about his own machines, but I can't 
remember the details. Once again, search results seem sketchy. Perhaps I 
need to go back and define my searches better...

For reference, I'm toying with Ubuntu in one spot, Debian Lenny in 
another, both referring to the same /boot and swap for - I think, in 
theory - ease.

Am I right? Wrong? In need of a good slap?

:) Best,

Dave
