1) A note first. I think the freeware unrar from one of the repositories can be added in the upcoming SL update releases, in the future. This is used by Archive Manager (file-roller) for uncompressing RAR files under GNOME. Name : unrar Arch : i386 Version: 3.5.4 Release: 1.2.el4.rf Size : 199 k Repo : installed Summary: Extract, test and view RAR archives Description: The unRAR utility is a freeware program, distributed with source code and developed for extracting, testing and viewing the contents of archives created with the RAR archiver version 1.50 and above. 2) What exactly is the bugfix repository? What is the difference between current erratas and bug fixes?
