I don't mind at all...

Well, no Dapper yet - I haven't been able to download it, but hopefully I
soon will have it.

Well, this gets a bit tricky as well. The last machine I did this on I
had to create separate directores under /boot to hold the kernel
images, the ramdisk image, system map, etc. It ends up looking
The /boot/ubuntu<release> directories hold the images for that release.
You have to edit the /boot/grub/menu.lst file to include the paths for the
images for this to work.
So to answer your question, yes, a single /boot for all OSes. I let the
for the latest Ubuntu release install it's version of Grub into the MBR,
look closely at the boot menu when I reboot. I have had to modify the boot
line once, as I recall, but it was pretty easy.

I do it after each install. This requires editing the /etc/passwd file to
have the correct paths to home directories, and also modifying the
defaults for useradd, but again, that's not too difficult. You just have
to remember to do everything.

See the explanation a couple of paragraphs above...
I hope this is clear and helpful. If you have any further questions
