BleachBit deletes junk to recover disk space and maintain privacy. It rids your system of old junk including cache, Internet history, temporary files, unused locale files (better than localepurge), logs, and cookies. Designed for Linux systems, it wipes clean 50 applications including Adobe Reader, Bash, Firefox, Flash, OpenOffice.org, Opera, Real Player, Skype, and more. It shreds files so that they cannot be recovered, and it wipes free disk space to hide insecurely deleted files. It offers both a simple PyGTK GUI and a command line interface for automation.
Cfengine is a tool for setting up and maintaining BSD and System-5-like operating system optionally attached to a TCP/IP network. You can think of cfengine as a very high level language, much higher level than Perl or shell: a single statement can result in many hundreds of operations being performed on multiple hosts. Cfengine is good at performing a lot of common system administration tasks, and allows you to build on its strengths with your own scripts.
Chev is a sane by default vulnerability check script that checks NIST and US Cert RSS feeds for a short list of software that you configure. It has two levels of priority, warn and critical, which allows for easy use with Nagios as a stand-alone script or in a cron job. Just add strings for your major pieces of software and chev will tell you when a vulnerability has been released.
Chiron FS is a FUSE based filesystem that implements replication at the filesystem level like RAID 1 does at the device level. The replicated filesystem may be of any kind you want; the only requisite is that you mount it. There is no need for special configuration files; the setup is as simple as one mount command (or one line in fstab).
Cleverbox provides an interactive command line shell dedicated to the deployment and maintenance of Trac and Subversion instances. It can handle multiple configuration profiles, enabling the deployment of differently flavored types of projects (Trac configuration and permissions, Apache configuration templates, etc). The project's main objective is to make your life as simple as possible. Thus, it comes with easy installation, easy upgrades, and a comprehensive documentation.
Common Configuration Parser (CCP) is a program that reads configuration files and upgrades them. It takes an oldfile (typically the configuration file currently in use) and a newfile (typically the default new configuration file) and optionally a template (a file that describes how the generated configuration file should look) and merges the files into one, creating a new configuration file that has the changes made to the old file in addition to the new options included in the new file. It is completely independent of the program that created the configuration file, and can be used for many different purposes such as merging changes between an old user-edited configuration file and a .rpmnew file generated by RPM during upgrades.
