Don't use tar or cpio for backups. I also use rsync for backups to other areas and remotely, so that might update atimes?

Okay, I didn't know that was there, but the logging I do is different. Would you mind going into details? Are you aware of /var/log/dpkg.log too? How about sending a patch to aptitude? In a nutshell, I capture all the standard output from an install in one file, together with a show of the package [as it was at install time] -- not sure I'll ever need to refer back to this. The other things I do are to keep a simple history of all aptitude use by logging the parameters used for each invocation. If packages are removed or installed, I create a new set of files that describes the installed packages -- this is so that I can track changes over time. All the extra stuff that I do is there to help documents somewhat changes to the system. At the end of the day, the standard /var/log/dpkg.log and /var/log/aptitude will probably give enough info for most people -- so I can't see any benefit in patching something that isn't broken, it is only different to the logging that I create for myself. My simple script is there for anyone who wants it -- it is pretty basic, but effective for my needs. I guess my main objective is to provide an historical picture of what was installed when and such information might be useful for machine rebuilds or as a reference for a completely new build on another machine. -- Kind Regards AndrewM Andrew McGlashan Broadband Solutions now including VoIP -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

how to tell what packages are unused on a debian server?
just a cleanup-related question but on a debian lenny server that i've inherited, i'm curious to know which packages have no value whatever and that i can delete. i recall there's a utility that will identify unused libraries but i'm curious about what else i can pinpoint that can be removed. this system is a web/mail server and, since its IP address is assigned statically and another system is responsible for all DNS/DHCP functionality internally, i conclude that i can remove the dhcp-related packages. that's just one example. any utilities that can help out in this regard? thanks. rday -- Robert P.

A Debian package called deborphan might be useful. When you remove items, you may want to purge them to be cleaner. Also, if you are not sure why a package is installed, you can do an aptitude why packagename and it will (hopefully) give you the extra information you need.
