userchroot is a small program which, in addition to doing a regular chroot, will also switch working directory once in chroot and drop privileges back to pre-suid values. It is intended to ease constructing chrooted user-driver services (running stfp-server in a restricted namespace for example). In order to conserve system resources, it is implemented in C. This makes it more suitable for higher load scenarios than scripts.
Userinfo is a console utility to display a variety of information about a local user. It uses loadable modules to perform different tasks, which separate the output with a field deliminator. Some may find it useful in shell scripts to gather information that might be tedious by other methods.
utfout is a command-line tool that can produce UTF-8 (Unicode) strings in various ways and direct them to standard output, standard error, or direct to the terminal without the need for shell support. Strings can be repeated, delayed, randomly-generated, written to arbitrary file descriptors, interspersed with other characters, and generated using ranges. printf(1)-style escape sequences are supported along with extended escape sequences. utfout(1) sits somewhere between echo(1) and printf(1).
util-vserver is a Linux virtual server utility framework, allowing an administrator to set up multiple, isolated virtual servers. It can be used to run various services securely separated, without requiring special configuration. Virtual servers are unable to interact with each other, or the main server.
MicroVGA-conio library is a minimalistic library for creating textual user interfaces on embedded devices running Linux or no OS at all. The library maintains compatibility with the conio.h console library and parts of the Unix curses library. The uvga-conio library can be used with almost every embedded system, starting with low-cost 8-bit MCUs such as i8051/PIC16/ATtiny, through 32-bit powerful system-on-chips (such as various ARM/MIPS systems), to fully-featured embedded Linux boards. A small but fully working conio application can fit into 4 KB of flash and 128 bytes of RAM. The library may be used with devices other than MicroVGA-TEXT interfaces.
