Spacewalk is a Linux and Solaris systems management solution. It allows you to inventory your systems (hardware and software information), install and update software on your systems, collect and distribute your custom software packages into manageable groups, provision (Kickstart) your systems, manage and deploy configuration files to your systems, monitor your systems, provision virtual guests, and start/stop/configure virtual guests.
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.
