Project Basics

This project is aimed at using an swap file on our Linux systems. We want to be able to generate an RAM size dependant swap file in /var, instead of using an fixed sized swap partition. And automatically regenerate the swap file if RAM size changes, to fit the new size.

This project has produced an dphys-swapfile script for sizing, setting up and mounting an swap file. And an init.d script that runs this script at boot and shutdown time.

This project was spawned from the dphys2 project (later replaced and made obsolete by the dphys3 project).

Project Status

For the full details of done/doing/todo of the project best read the Logfile. A short excerpt from it is here:

Done are:

Milestone/Release 4 (2004.02.19):

This was still as part of dphys2. Made dphys-swapfile script to automatically generate/resize and activate an swapfile, default 2*RAM size, and also deactivate and delete it at the approriate times

Milestone/Release 5 (2004.07.29):

Split out of dphys2 into an separate project, as this tool is also usefull without dphys2, on any Linux system
Reworked as separate /sbin and /etc/init.d scripts

Milestone/Release 6 (2006.09.15):

Repackaged as separate non-debianised upstream for later debianisation by separate maintainer
Slight code and documentation improvements

Milestone/Release 7 (2006.10.20):

Code and docs tidy up, extensive quoting improvements, no absolut paths in commands
