BG-Rescue Linux is a Busybox and uClibc-based rescue system with a 2.4 series Linux kernel. It supports full read/write support for NTFS using ntfs-3g. It is loaded from two floppy disks, a bootable CD-Rom, or a USB Stick. The system runs entirely in RAM. It supports a wide range of hardware (including SATA and DM/LVM2) and filesystems (including ext2/3, hfs/hfs+, and xfs) and can serve as a full backup/restore system for MS Windows systems which use FAT12/16/32 or NTFS. It also includes many utilities, including strong compresstion tools like lrzip. Automatic loading of the antivirus-program F-Prot from cdrom or usbstick is supported.
NASLite is a Network Attached Storage (NAS) server operating system designed to transform a basic computer into a dedicated file server. Utilizing highly optimized versions of Samba, uCLibc, BusyBox, and various other Linux tools, it provides SMB/CIFS, FTP, or NFS filesystem support. It accommodates multiple client OSes: Windows, Mac OS X, and Linux. NASLite offers SMART disk monitoring and large file support, and is incredibly easy to install and administer.
BG-Tiny Linux Bootdisk is a Linux bootdisk that does not use a ramdisk, so it will run on computers with very little RAM. It is basically a somewhat extended fork of Tiny Linux Bootdisk. It is based on Linux 2.4 series, uClibc, and BusyBox. It includes dosfsprogs, e2fsprogs, gpart, lilo, and ms-sys. Supported filesystems are ext2, ext3, iso9660, tmpfs, and vfat.
Salvare (from the Latin "to rescue") is a small Linux distribution designed for small, credit-card sized CDs which typically hold around 34MB. More Linux than tomsrtbt but less than Knoppix, it aims to provide a useful workstation as well as a rescue disk. In addition to providing a rescue environment similart to tomsrtbt, it adds OpenSSH, a graphical and text mode Web browser (Links), security tools such as chkrootkit, nmap, and tcpdump, the ability to apt-get install additional software from Debian into tmpfs, the ability to run entirely from RAM, and much more. It's also customizable using a simple source-code based package management system.
alcolix is a minimal Linux rescue distribution with the goals of being small, compatible, and very usable. It has a cozy shell and a multitude of partition rescue/editing tools, all based on up-to-date releases (e.g., 2.4.x kernel with USB support). It uses cpio.bz2 data disks and has a full GRUB bootloader, memtest86, and more.
PXE Knife is a tool for booting various floppy based utilities via syslinux, allowing them to be booted off a CD, a hard drive, or over the network via PXE. PXE Knife can be used with a number of commonly used tools such as hard drive manufacturer's utilities, memory testers, Linux recovery disks, Windows password changers, pre-configured PXE Knoppix booters (just add DVD), and a number of other utilities. It takes advantage of syslinux's menu system, so it's easy to navigate.
NanoNAS is a Network Attached Storage (NAS) server operating system designed to transform a basic computer into a dedicated HTTP, SMB/CIFS, or AFP file server. It fits on a single floppy disk and is intended for use in any low-security environment or application that requires the simultaneous availability of large amounts of inexpensive networked storage.By design, it is a community workgroup server and does not support features such as user management, disk quotas, or the ability to join domains. However, it is very easy to set-up, to administer, and to use.
