+**NOTE:**  **sysv-rc-conf** provides a terminal GUI for managing /etc/rc{runlevel}.d/ symlinks.
 The interface comes in two different flavours, one that simply allows turning services on or off and another that allows for more fine tuned management of symlinks.
 Unlike most runlevel-config programs, you can edit startup scripts for any runlevel, not just your current one.

-**fsarchiver** is a system tool that allows you to save the contents of a file-system to a compressed archive file.  The file-system can be restored on a partition which has a different size and it can be restored on a different file-system.  Unlike tar/dar, FSArchiver also creates the file-system when it extracts the data to partitions.  Everything is checksummed in the archive in order to protect the data.  If the archive is corrupt, you just loose the current file, not the whole archive.
