Fedora 18, dubbed “the Spherical Cow,” was finally released on Jan. 15 after seven postponements that stretched two months beyond its scheduled six-month release cycle. Despite some noteworthy improvements overall to the operating system, I found little about Fedora 18 to justify adopting it over other Linux distros or upgrading to it from an earlier version. Two software items caused the release delays. One was Anaconda, a revamped installer, and the other was FedUp, a new Fedora upgrade utility.
