Pádraig Brady has announced GNU Core Utilities (coreutils) version 9.12. "There have been 288 commits by 16 people in the 21 weeks since 9.11". New features include an -A option for uname which labels all output, as well as adding awareness of the failfs and nullfs file types to stat and tail. There are many in this release as well, including a fix for a bug "present in 'the beginning'" that caused some utilities to fail when traversing hierarchies if files are being removed in parallel.
