Here is one late change to the Fedora Packaging Guidelines:
The systemd scriptlet guidelines have been updated for Fedora 18. In
Fedora 18, the systemd package now provides helper macros to simplify
%post, %preun, and %postun invocations in packages with systemd unit
files. Additionally, these macros enable support for systemd "profiles",
a Fedora 18 Feature.
This guideline change was approved by the Fedora Packaging
Committee (FPC), but was delayed until recently, pending Feature
approval of the systemd "profiles" feature.
Many thanks to Lennart Poettering, and all of the members of
the FPC, for assisting in drafting, refining, and passing these guidelines.
As a reminder: The Fedora Packaging Guidelines are living documents! If
you find something missing, incorrect, or in need of revision, you can
suggest a draft change. The procedure for this is documented here:
