I'm glad to announce that as of yesterday Koschei production instance
has been moved Fedora infrastructure and now it can be considered as
officially-supported Fedora service.
Koschei is a continuous integration service for Fedora packages.
Koschei is aimed at helping Fedora developers by detecting problems as
soon as they appear in rawhide - it tries to detect package FTBFS in
rawhide by scratch-building them in Koji. More information can be
found at Fedora Wiki .
Interested parties can be automatically notified when Koschei detects
change in package FTBFS status. In order to subscribe to email or IRC
notifications you can follow instructions at .
At the time of writing, Koschei monitors about 20 % of all Fedora
packages, but anyone with FAS account can add packages they are
interested in. See  for details how to add packages to Koschei.
I would like to thank everybody who helped to make Koschei at Fedora
infrastructure possible, especially Kevin Fenzi, who sponsored Koschei
request for resources and assisted us with the migration.
