Foresight Linux Newsletter – Issue 02 2011
Foresight Linux – SE got a facelift, alot easier to find information for our swedish users. Thanks for all feedback.
Last newsletter was mostly to get information about developmet information. This newsletter is little more about system model and updated packages.
A new update mechanism called “system model” is added. In this model, a file called /etc/conary/system-model describes what should be installed on the system. This file is modified by certain conary update commands, and can also be edited with a text editor. The system model allows a system to be updated relative to a search path that includes groups as well as labels, leading to more coherent sets of updated packages. It also allows re-starting updates with transient failures; the filename /etc/conary/system-model.next is reserved for storing the system target state during an update operation.
The system model mode is intended to become the normal update mode Â for Conary-based Â systems Â in Â the Â future. Â It works by creating a set oftroves that define the system, and then moving the system to that defiâ€nition. Â It is conceptually similar to building a group into a reposiâ€tory Â and Â then Â migrating Â to Â that Â group. Â Significant Â differencesinclude:
- Â Â Â In Â a Â group, all trove references are absolute, but in a model,you can choose whether references are absolute. Â Migrating to Â aspecific Â version Â of a group will always move the system to theexact set of packages referenced, but re-applying a system modelwill Â update Â troves that are not pinned down to a specific verâ€sion.
- Â Â Â There is no group name for the set of troves.
- Â Â Â There is no version for the set of troves. Â (The version Â operaâ€tion in a system model does not provide conary versioning.)
- Â Â Â Path Â and Â version conflicts are not checked when assembling theset of troves. Â (No group policy is run Â at Â all.) Â This Â meansthat Â path Â and Â version Â conflicts Â will Â be Â found Â only whileinstalling the packages.
A system model that installs only a single group will functionsimilar to migrate mode. Â The most obvious difference is Â that Â migratemode Â honors Â variations Â in Â byDefault settings in the system database(that is, an optional component of the trove(s) migrated Â to Â that Â hasbeen Â installed on the system will still be installed after the migrateoperation finishes), whereas a system model update honors those changesonly if they are represented in the model itself.
Next Foresight Linux iso will have system model enabled as default.
If you want to run it today in Foresight, open Terminal and write this command:
PackageKit is soon available as default in Foresight again. read more at: Og Maciel blog
To install it today, open terminal and write: sudo conary update PackageKit gnome-packagekit
GTK3 is now in Foresight Linux, first step against FL3 and Gnome 3.
Next release versions will be 2.5.1, 2.6 and 3.0
