Bug#82615: What about swapd?
Nothing wrong with having two packages with the same functionality, but I
think you might want to know about swapd:
anthony@bohr:~$ dpkg -s swapd
Status: install ok installed
Maintainer: Aigars Mahinovs <email@example.com>
Depends: libc6 (>= 2.2.2-2)
Description: Swap demon for dynamic swap file creation
Swapd is a dynamic swapping manager for Linux. It provides the system with
as much swap space (virtual memory) as is required at a particular time by
dynamicly creating swap files. This is more convenient than using fixed swap
files and/or partitions because they (a) are unused most of the time and are
just taking up disk space; and (b) provide a limited amount of virtual
On systems that have constant need for virtual memory it would still be
wise to use a swap partition in parallel with dynamic swapping, since swap
partitions provide much faster access than swap files.
