Re: Using wheezy or squeeze.
If you're really paranoid, I suppose you have three servers: Live, Copy-of-Live and Development. :) I wouldn't call that paranoid at all, I'd call that good practice... Use 'stable' (Copy-of-Live) to check your application will run ok with the packages/versions available on squeeze. Sometimes it'll mean falling back to backports, creating your own backport, or adjusting your application. I've found such problems on several occasions - developing on testing and finding a dependency wasn't available in squeeze, was too old to support feature X, or a library's API had changed. Use 'testing' (Development) to check there're no surprises when testing becomes the new stable. One memorable one that came up in the lenny-squeeze transition was the removal of the MySQL Cluster engine from MySQL Server between 5.0 and 5.1 (the projects forked). -Steve On 9 January 2013 13:48, Darac Marjal mailingl...@darac.org.uk wrote: On Thu, Jan 10, 2013 at 12:25:47AM +1300, Chris Bannister wrote: On Wed, Jan 09, 2013 at 10:58:01AM +, Darac Marjal wrote: This is the whole point of the testing distribution, AFAIUI.

If there are only a few packages you need from testing (wheezy), you should not upgrade your entire system to wheezy and instead only get the newer packages you need. First, see if they have been backported to squeeze: http://backports-master.debian.org/. If they're not in squeeze-backports, get the Debian source packages from wheezy and build them on your squeeze system. I'll let someone who is more familiar with the Debian packaging tools instruct you on this, but BE SURE TO VERIFY THE SIGNATURES OF THE SOURCE PACKAGES! Don't worry too much about this. Debian Backports fully supports secure-apt (that is, you add a line to your /etc/apt/sources.list and apt-get/aptitude will warn you if there is a problem with signatures). As to the original question, I would suggest installing wheezy NOW on your test server. You will probably want some time to configure and test the server before deploying it in production. Wheezy will be going stable soon (a couple of months is the last estimate I heard) so you should be fine there. This is the whole point of the testing distribution, AFAIUI. You run 'stable' on your production server and 'testing' on your development server. You do your development and testing of the newer version on your development server and when that distribution is released, you're in a good position to update the production server with minimal impact (because you already know how the changes will impact your userbase). The production server then remains with a relatively fixed set of software. Apologies if this sounds like teaching you to suck eggs. signature.asc Description: Digital signature

Using wheezy or squeeze.
People, I have used debian 6.0 squezze, and some packages is old, since the wheezy, have a packages new version. I need to install a mail server with potfix, LDAP, e Cyrus IMAP. I want install version Cyrus 2.4, is in squeeze is 2.2. Can I to trust in Wheeezy ? Rodrigo Faria
