Finnix
Finnix is a Debian-based Live CD operating system, developed by Ryan Finnie and intended for system administrators for tasks such as filesystem recovery, network monitoring and OS installation. Finnix is a relatively small distribution, with an ISO download size of approximately 100 MiB, and is available for the x86 and PowerPC architectures, and paravirtualized (User Mode Linux and Xen) systems. Finnix can be run off a bootable CD, a USB flash drive, a hard drive, or network boot (PXE).
History
Finnix development first began in 1999, making it one of the oldest distributions released with the intent of being run completely from a bootable CD (the other Live CD around at the time was the Linuxcare Bootable Business Card CD, first released in 1999). Finnix 0.01 was based on Red Hat Linux 6.0, and was created to help with administration and recovery of other Linux workstations around Finnie's office. The first public release of Finnix was 0.03, and was released in early 2000, based on an updated Red Hat Linux 6.1. Despite its 300 MiB ISO size and requirement of 32 MiB RAM (which, given RAM prices and lack of high-speed Internet proliferation at the time, was prohibitive for many), Finnix enjoyed moderate success, with over 10,000 downloads. After version 0.03, development ceased, and Finnix was left unmaintained until 2005.
