The Creative
Commons CC0 license is essentially a public-domain declaration (or as
close as is possible in jurisdictions that lack a public domain). The
Fedora project has allowed the distribution of code under this license,
but, as announced
by Richard Fontana, that policy is changing and CC0 will no longer be
allowed for code:

The reason for the change: Over a long period of time a consensus
has been building in FOSS that licenses that preclude any form of
patent licensing or patent forbearance cannot be considered
FOSS. CC0 has a clause that says: “No trademark or patent rights
held by Affirmer are waived, abandoned, surrendered, licensed or
otherwise affected by this document.”

Existing CC0-licensed packages may be grandfathered in, but that evidently
has not yet been decided.
