UnusedPkg is a diagnostic tool to search the oldest unused packages in your Linux system. UnusedPkg prints a sorted list with the size and number of days that a package has been idle. This helps you determine what packages can be manually removed to clean the system. It supports any apt-based distribution (tested on Debian and Ubuntu) and Slackware.
The Zumastor Linux storage project adds enterprise storage features to Linux, primarily improved snapshots and remote replication. Point-in-time, near zero-cost, block level snapshots can be added to any existing filesystem and performance does not degrade with multiple snapshots. Remote replication is achieved by sending minimal block level deltas between snapshots without having to traverse the entire filesystem like rsync does.
rootpretender is a system that enables special file operations such as the creation of block special and character special device nodes and unlimited chown()ing of files for non-root users of Unix systems. It does this by faking special file operations. For example, chown() is not executed, and mknod() creates regular files instead of device nodes. These operations are remembered, so next time a process under rootpretender's control examines an affected file with stat() or a similar system call, the fake information is returned. It uses LD_PRELOAD and includes patches for rsync 2.6.6 and rsync 2.6.9 for use on systems without LD_PRELOAD support. These make it possible to copy file ownership and device nodes even if root access is not available on the target.
cpverify verifies that a file or directory structure has been copied or burned without errors. That is, it ensures that the copied data is exactly the same as the original. This is done by calculating and comparing a cryptographic checksum using the MD5 message-digest algorithm on each file from the source and the copy destination.
Laptop Mode Tools allows you to control various power management settings based on AC/battery power state. Among other things, it controls Linux's "Laptop Mode" feature that allows your hard drive to spin down for extended periods. It can also control CPU frequency scaling and screen blanking timeouts (both terminal and X). It supports automatic hibernation when battery is low.
Plash is a sandbox for running GNU/Linux programs with minimum privileges. It is suitable for running both command line and GUI programs. It can dynamically grant Gtk-based GUI applications access rights to individual files that you want to open or edit. This happens transparently through the Open/Save file chooser dialog box, by replacing GtkFileChooserDialog. Plash virtualizes the file namespace and provides per-process/per-sandbox namespaces. It can grant processes read-only or read-write access to specific files and directories, mapped at any point in the filesystem namespace. It does not require modifications to the Linux kernel.
