Webfs (a.k.a. webfsd) is a simple HTTP server for purely static content. You can use it to serve the content of an FTP server via HTTP, for example. It can also be used to quickly export some files by starting an httpd server in a few seconds, without editing config files first. It knows how to use sendfile() on linux and FreeBSD. There is also sendfile emulation code which uses read()+write() and a userland bounce buffer; this allows one to compile and use webfs on systems without sendfile(). The stripped binary is less then 32Kb, making it great for floppy distros, recycled hardware, embedded systems (cramfs/romfs/flash disk) and other resource-limited environments.
The Parallel Virtual File System is a user-space parallel file system for use on clusters of PCs (and Beowulfs in particular). It provides transparent file striping across multiple machines and includes a loadable kernel module for use with existing binaries. TCP/IP is used for data transmission, and file data is stored on existing file systems on each machine.
noflushd is a simple daemon that monitors disk activity, spins down disks whose idle time exceeds a certain timeout, and stops writes to them in order to keep them spun down as long as possible. It's mainly used on laptops to save power, but can also be useful to desktop users with noisy hard disks. noflushd requires a kernel thread named kupdate which is present in Linux kernel version 2.2.11 and later. For earlier kernels, bdflush version 1.6 provides equal functionality.
EzRPM takes one or more RPM packages as parameters and installs them handling all dependencies by installing additional RPMs as necessary. These RPMs are located by scanning all directories in the original list of RPMs to be installed, and by scanning the paths in the RPMPATH environment variable.
ProcMeter3 is a program for monitoring the system status and other information and displaying it in a series of graphs or as text. Most of the information comes from the /proc filesystem (cpu usage, load average , processes information, memory usage, network traffic, interrupts etc.). Other information is available for other sources (date, time, email status, log file length, disk status etc.). The program is modular and highly configurable.
