Critical path package
A critical path package is a specially managed package in Fedora that provides some essential or core functionality. Updates for critical path packages must undergo additional verification before they can be distributed to the community at large.
Previously, documented policy treated every package the same. While good for uniformity, in reality certain packages require extra attention and care when updating and testing. These packages have potential to break the critical path of use of our Fedora distribution. As part of a Fedora Activity Day, several contributors proposed a critical set of actions that must not be broken. The packages required to sustain these actions make up the critical path.
Packages within the critical path are required to perform the most fundamental actions on a system. Those actions include:
- graphical network install
- post-install booting
- decrypt encrypted filesystems
- get updates
- minimal buildroot
- compose new trees
- compose live
A set of groups are defined in the
comps.xml file to include packages required for the critical use cases listed above. Since package dependencies change regularly, the
comps.xml groups are then used to dynamically generate the list of packages.
The critical path package groups in
comps.xml are listed below:
@core @critical-path-base @critical-path-gnome @critical-path-apps @critical-path-kde @critical-path-lxde @critical-path-xfce
For more information on
comps.xml see how to use and edit comps.xml for package groups.
If a package is added to the critical path list as a result of normal package dependency the package maintainer will be notified through direct email and the extra processes they have to go through. (IS THIS TRUE)
If they do not wish to maintain the packages with these extra processes then they have to orphan the package. A new maintainer will need to be found.
The proventesters FAS group is responsible for ensuring minimal disruption to the critical actions listed above. If you would like to join proventesters, check out Proven_tester, where you will also find instructions on the testing process.
