Because PM can be a complex and varied subject, I would suggest that we start small. Start with a POC LFS that employs DESTDIR and a _very simple_ way to package. The two main initial goals might be: 1. Know what files have been installed by the package and where they were installed. 2. Store the compiled package for possible use on another system. It would be very easy to accomplish that with tar only: make DESTDIR=/tmp/package install cd /tmp/package tar -cjf package.tar.bz2 ./ tar -tf package.tar.bz2 >/var/packagedata/package cd / tar -xf /tmp/package/package.tar.bz2 The above commands could probably be condensed even further or made slightly more robust, but it should demonstrate how easy it is to keep track of installed files. As we develop the idea further, and we wish include educational points in LFS about more advanced concepts of Package Management, we could bring in other features. -- JH -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
