Fedora Update Notification
FEDORA-2012-6674
2012-04-26 19:20:08
--------------------------------------------------------------------------------
Name : puppet
Product : Fedora 17
Version : 2.7.13
Release : 1.fc17
URL : http://puppetlabs.com
Summary : A network tool for managing many disparate systems
Description :
Puppet lets you centrally manage every important aspect of your system using a
cross-platform specification language that manages all the separate elements
normally aggregated in different files, like users, cron jobs, and hosts,
along with obviously discrete elements like packages, services, and files.
--------------------------------------------------------------------------------
Update Information:
With Fedora 17 using ruby-1.9.3, an update to puppet-2.7, which has improved
support for ruby-1.9, is required. Note that ruby-1.9 is not fully supported in
the puppet-2.7 series. Where possible, patches from the next upstream release
branch will be backported to improve ruby-1.9 compatibility.
Also note that there will likely be issues when connecting to a puppet-2.6
master. This is unavoidable for the moment. Normally all Fedora and EPEL
branches are kept in sync to avoid this problem. At this time, a decision to
move all branches to 2.7 has not been made.
This update obsoletes puppet-2.6.16, which fixed several security issues
recently found in puppet related to filebucket functionality. For full details,
refer to the upstream release notes:
http://projects.puppetlabs.com/projects/1/wiki/Release_Notes#2.7.13
