Project Atomic, a Red Hat sponsored project, features an interesting new update system for RPM-based Linux operating systems called OSTree (rpm-ostree) which has been developed by Colin Walters over the last couple of years. Evidently OSTree supports atomic updates to an OS although I am not sure how that actually works because there is a lot of marketing hype and buzz words associated with Project Atomic including Docker containers. In the default model, the RPMs are composed on a server into an OSTree repository, and client systems can replicate in an image-like fashion, including incremental updates. However, unlike traditional Linus In this post, I explore how to use the YUM history database to trace the timeline (installation, updates and removal) of RPM packages on modern RPM-based Linux distributions. A couple of months ago, the PackageKit utility on my Fedora 18 system stopped working. YUM continued to work so I had an easy workaround and did not really try to trace down the problem and fix it. I assumed that a future version of a PackageKit RPM would fix the problem. Recently I did a FedUp upgrade to Fedora 19 and the problem persisted so I decided the time had come to investigate the root cause of the problem and fix it. Here is how the problem manifested itself: A quick check of Fedora Bugzilla convinced me that the The latest version of RPM (4.10) that was recently released supports dpkg-style tildes (~) in version/release strings. The tilde character can be used to append a label such as “beta” to a package without actually incrementing the version of the package. For example – package-1.0~beta. In this case, the package package-1.0~beta would not replace package-1.0 as the former package is considered to be an older version, even if it was released later. See here for more information. |
