Ibnstall Eats Swap Partitions On Non-Installation Drives

I agree with you - i can't think of any reson you'd *want* your new distro 
to use the swap partitions for the old distro... but I also don't see what 
the problem is. 

o Any and all swap partitions you have defined will be initialised and
mounted by whatever distro you're running, at boot time anyway... You wont
be saving data to a swap partition for use later, so formatting them as
part of the install wont be a problem.

o The fact is that the installer wants to give the system the maximum 
amount of swap space, by using any swap partitions it finds. I don't see 
why that would be a problem. It's perfectly reasonable for you to disable 
access to that swap partition after boot.

o The format for a swap partition is the same accross the board. IMHO, I 
think any changes to the format for linux swap would be made in the 
kernel, and would affect all distros at the same time. So there wont be 
any major problem with one distro formatting another distros swap
