I understand that a single linux swap partition could work as a swap partition for multiple distros, but could I use the same partition as a FreeBSD swap partition?
When I installed 12.04 Precise 64bit, I created a 16Gb swap partition. I know, I'm an idiot! After months of use, I never once saw the swap use more that about 300kb of hd space. Because of this, I shrunk the swap partition down to 4Gb. I didn't want to eliminate it altogether as I've read this can cause problems.
