Debian packaging utilities for Truecrypt source helps to get Truecrypt running with a minimum of effort under Debian-based Linux systems (Debian and Ubuntu are officially supported). Truecrypt is an open source disk encryption software which uses a concept of containers to store encrypted data. The containers (or volumes) can be read transparently under Linux and Windows. The utilities create installable *.deb packages from the sources and those debs can be used in turn to install the encryption software.
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.
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.
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.
