This system daemon for the Linux kernel aims to do away with the need for large, fixed swap partitions or swap files.
When installing a Linux-based system (invariably GNU/Linux) with Swapspace, the usual swap partition can be omitted, or it can be kept quite small. Whenever Swapspace finds during normal system usage that more virtual memory is needed, it will automatically claim space from the hard disk. Conversely, swap space that is no longer needed is freed up again for regular use by the filesystem.
This means that with Swapspace installed, sizing the system’s available swap space during installation is no longer a life-or-death choice. It now becomes practical to run GNU/Linux off just a single, big partition–with no disk space lost to regrettable installation choices. The system should also be able to handle the occasional memory-intensive task that takes much more swap space than was originally foreseen, without leaving the same swap space unused and unusable during normal operation as is normally the case.
