Well, you can only have one thing called /boot per instance of an OS. 
So, you will need another name for the "other" OSes /boot in each 
instance.  So, say that the KRUD /boot is hda1 and the RH /boot is hdc1, 
call the hdc1 /rhboot (or hell, /mnt/rhboot) in KRUD and call hda1 
/KRUDboot in RH.

To say all this in another way; each OS instance is clear on what /boot 
is, but they disagree, and I think that it is ambigious in your mind (it 
isn't to the SW ;-)

I don't have a lilo.conf handy, but you need something like:

(in KRUD)

label=KRUD
image=/boot/linux

label=RH
image=/rhboot/linux

(and in RH)

label=KRUD
image=/KRUDboot/linux

label=RH
image=/boot/linux

(Note that I'm not 100% sure of any of the syntax above, I'm just trying 
to illustrate the point.)

The point here is that both of the above are equivalent when you expand 
the mount points to devices.

I hope I made it better, not worse :-)
