Assign existing Ubuntu swap for FC8 install?

How do I do this?

I have created 2G root partition, 10G left that's free, and I want to assign FC8 to use existing swap.

Also, FC/RHEL Bible says 2G max swap, but my Ubuntu swap partition is 3.7G. Does that matter?

Fedora will probably pick up the existing swap and offer to use it. Else there must be an option at the partitioning stage - I share swap between F10 and five other systems. Maybe an "expert" option.

As for the size, don't worry about it - only 2 Gig will be used (even by Ubuntu). Be aware that if Anaconda does a mkswap, that will change the UUID, and Ubuntu won't be able to use it until you fix fstab (on Ubuntu)

Thanks syg...

But now I'm seein' a mod in another Linux forum who says all Linuxes [Linii?] recognize existing swap... EXCEPT Fedora.

???

That'll teach you to ask in more than one place ...
Must be do-able; and it can't be too obtuse or I would have remembered doing it.

I got the install complete, but I installed no grubloader, opting to use the one for Ubuntu.

It isn't appearing in Ubuntu grub menu, and I did update grub. It said 'updated', but I think the old kernels are filling up the menu, and not allowing FC8 to appear.

How to delete old kernels???

That was probably a mistake.

Irrelevant - grub doesn't search for other systems to include in the boot list; that's done by the (distro) installer at initial install.
You'll have to add the Fedora stanza(s) manually - and update them in the unlikely (for F8) event new kernels ship.
Would have been better to install the bootloader to the root partition and simply chainload to it from Ubuntu.

(You should probably start a new thread for this).
