Never done that before.
If you try, make sure that you clean the swapfile in the shutdown script.
i.e. Unmounting it, formating it as swap and then continue reboot.
For both RH as Gentoo.
This way you know that the swap stays empty.

I don't know if this is needed, but I would figure you don't want swap remnants from either distro to be available to the other...

Long time ago we had a system that had a seperate partition for use as both Windos swap partition as linux swap...

but how can i edit the shutdown script?

My slackware has in the dir : /etc/rc.d a file called rc.6.
But I'm not sure if Gentoo uses that same script.
With Red Hat and Fedora you need to create a script or edit an existing one in the /etc/rc.6 directory.

The commands to add are :

(Swap partition for this example: /dev/hda6)

swapoff /dev/hda6
mkswap /dev/hda6

First line turns the current swapfile off.
Second line creates a new empty swap on the swappartition.

Better ask a Gentoo expert on how to incorporate this....

done it many times and have had no problems. Maybe because I have so much RAM that my swap partition never gets looked at.

have fun

I don't think you have to format it either, because after a reboot its newer read from untill you overwrite the old stuff.

Good luck
