Re: Reinstalling Packages after Rebuilding System with Etch

[Carlos Bergero <rak@fcien.edu.uy>]

Martin:
           First you dont have to reinstall, you can change the 
soureces.list file, replacing the sarge with etch, and then do an 
apt-get update, apt-get dist-upgrade, that's will take some time and 
bandwith, but few things get brocken. Well actually several, didn't work 
after I upgrade my mail server, postfix, amavisd, clamav, spamassassin, 
gld, mailman, dovecont, and a few non importan web stuff, mysql and 
postgres. Some stuff needed work to get back on line but I fix it and it 
was faster than clean install/config  everithing. What I do advice you 
to do in case u have spare box or backup space is to backup the entire 
instalation. Or better if u have s imilar box mirror copy the server 
there and then test the update there, to see what gets broken and how do 
you fix it.
Cheers, and good luck
