I certainly see the difference between backing out one rpm vs. a while distro upgrade.
Without seeing the requests "people" are asking you for which you're trying to respond to, I can't speculate whether they want to back out a full distro or just a honked upgrade of a few things, or both. I'd suggest they folks who need rollback might perhaps need to learn how to do things like VMware snapshots (or the like) and actually testing upgrades in sandbox systems before applying upgrades to production systems, but I've been around long enough to know most folks don't normally go to that level of rigor. They launch and pray almost always. Me too. I don't see a reasonable way to back out a full distro upgrade. It's possibly possible to do it for simple version upgrades or a rpm or two. Good example to try would be net-snmp or a perl/python module or something else like that which has a lot of tentacles and yum ripple to deal with. ------ [EMAIL PROTECTED] ------ -----Original Message----- From: Seth Vidal [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 05, 2008 12:01 PM To: yum development Subject: Re: [Yum-devel] pain and suffering and allowdowngrade > Confused. > > Historically there are feature requests for relatively easy things that > have been denied due to fear of (1) below.

I want to go backward from here for this package and I don't know what deps it just pulled in for this upgrade so figure that out." My concern for downgrade is not the above. It is the people who want downgrade to be an entire distro downgrade. Or they want it to actually be a real 'rollback' which implies a great deal more than just downgrading a set of pkgs. Do you see the difference from my perspective? -sv _______________________________________________ Yum-devel mailing list Yum-devel@lists.baseurl.org http://lists.baseurl.org/mailman/listinfo/yum-devel _______________________________________________ Yum-devel mailing list Yum-devel@lists.baseurl.org http://lists.baseurl.org/mailman/listinfo/yum-devel
