"Gujin is a PC boot loader which can analyze your partitions and filesystems.

It finds the Linux kernel images available, as well as other bootable partitions (for *BSD, MS-DOS, Windows, etc.), files (*.kgz) and bootable disk images (*.bdi), and displays a graphical menu for selecting which system to boot.

Gujin boots Linux kernel using the documented interface, like LILO and GRUB, so it doesn't need any other pre-installed bootloader. It can also directly load gzip'ed ELF32 or ELF64 files, with a simple interface to collect real-mode BIOS data. There is no need to execute anything after making a new kernel: just copy the kernel image file into the "/boot" directory, with a standard name.

Gujin is written almost entirely in C with GCC, and it fully executes in real mode to be as compatible as possible."

"The Window Manager for Smart Windows [...]

CTWM is an extension to twm, originally written by Claude Lecommandeur
(see README.Claude for his README), that support multiple virtual
screens, and a lot of other goodies.

You can use and manage up to 32 virtual screens called workspaces.
You swap from one workspace to another by clicking on a button in an
optionnal panel of buttons (the workspace manager) or by invoking a
function.

You can custom each workspace by choosing different colors, names and
pixmaps for the buttons and background root windows.

Main features are :

- Optional 3D window titles and border (ala Motif).
- Shaped, colored icons.
- Multiple icons for clients based on the icon name.
- Windows can belong to several workspaces.
- A map of your workspaces to move quickly windows between
different workspaces.
- Animations : icons, root backgrounds and buttons can be animated.
- Pinnable and sticky menus.
- etc...

The sources files were once the twm ones with only workmgr.[ch] added
(written from scratch by Claude Lecommandeur). There were also some
modifications to some twm files. This was back in CTWM version 1, by
now, there are a bit more changes and a few more additions. It's
possible, thought it's doubtful, that twm patches can still be
applied... with great care."

"LXDE is a new project aimed to provide a new desktop environment which is lightweight and fast. It's not designed to be powerful and bloated, but to be usable and slim enough, and keep the resource usage low. Different from other desktop environments, we don't tightly integrate every component. Instead, we tried to make all components independent, and each of them can be used independently with few dependencies."

"Splashy is a next generation boot splashing system for Linux systems. Unlike other splashig systems, it needs no patches to the kernel and it’s installed like a normal package. Make your boot process eye-candy with Splashy!

Some of Splashy’s most noticable features include:

* Require zero kernel patches/full functionality in user-space
* Boot/halt/reboot/runlevel-switch support
* Progressbar support (with optional border)
* Verbose mode (with F2/ESC keys)
* Configuration file in XML
* Cope with any video-mode resolution/size
* Cope with 8, 16, and 24 bit framebuffers
* Alpha channel (transparency) support
* Video mode detection
* Initramfs support
* TrueType2 fonts support
* Lots of image/animation file formats supported: jpg, png, gif, mpg, swf
* Low dependencies and code in C to best perform
* Full LSB support
* Multiple themes support
* Really easy to create new themes
* X detection on exit
* Smooth progressbar movement
* Animations support
* Fade in/out effects
* Totally configurable"

"Smart Boot Manager (SBM) is an OS independent and full-featured boot manager with an easy-to-use user interface. There are some screen shots available.

The main goals of SBM are Absolutly OS independent, Flexable and Full-Featured. It has all of the features needed to boot a variety of OSes from several kinds of media, while keeping its size no more than 30K bytes. In another words, SBM does NOT touch any of your partitions, it totally fits into the first track (the hidden track) of your harddisk!

SBM now supports booting from floppy, harddisk and CD-ROM. ZIP and LS-120 are planned to be supported recently"

"FunionFS means an Union filesystem for the FUSE[*] driver.
This program works only with the Fuse driver which is natively included since the 2.6.14 Linux kernel.

Above all, what is an Union filesystem?

It is a method used when one wants to manufacture LiveCD Linux such as Knoppix: support (CDROM) is only a read-only one.
The operating system, however, needs to write on this filesystem.
The method consists in superimposing (Union) on the read only filesystem, a small size read-write one.
This filesystem (often stored in a RAMDISK) contains all the modifications made by OS on the CDROM content.
This method is often used for of Linux Stored in a PROM or a compressed file like in CRAMFS."

* "With FUSE it is possible to implement a fully functional filesystem in a userspace program. Features include:

* Simple library API
* Simple installation (no need to patch or recompile the kernel)
* Secure implementation
* Userspace - kernel interface is very efficient
* Usable by non privileged users
* Runs on Linux kernels 2.4.X and 2.6.X
* Has proven very stable over time"

"This is the home of the graphical boot process for the linux kernel although it is not yet a part of the official kernel. It is, however included in several major distributions. [...]

Features:

* Nice graphics (JPEG)
* Antialiased text rendering (TrueType)
* Animations (MNG)
* Progress Bar
* Display of boot messages above or below a graphic. ("verbose" and "silent" modes)
* Fully themeable"

"MapFS implements a Linux filesystem which utilizes copy-on-write functionality and existing Linux filesystems to allow component filesystems (or portions thereof) to be combined into a single virtual filesystem that appears to be fully writable. It is written in C, uses the standard Linux kernel VFS and loadable module interfaces for defining new filesystem types to the kernel, and supports (at least) kernel versions 2.4.7 to 2.6.13."

"Squashfs is a compressed read-only filesystem for Linux. Squashfs is intended for general read-only filesystem use, for archival use (i.e. in cases where a .tar.gz file may be used), and in constrained block device/memory systems (e.g. embedded systems) where low overhead is needed. The filesystem is currently stable, and has been tested on PowerPC, i586, Sparc and ARM architectures."
