In order to save disk space, I want to have two OS installations share a single swap partition (a dual-boot). Is this a good idea?
Are there any side effects when two distros share a swap partition?
partition;swap;dual boot
It's possible. In fact, you can share the swap space between completely different operating systems, as long as you initialize the swap space when you boot. It used to be relatively common to share swap space between Linux and Windows, back when it represented a significant portion of your hard disk.Two restrictions come to mind:The OSes cannot be running concurrently (which you might want to do with virtual machines).You can't hibernate one of the OSes while you run another.
