Finnix is a self-contained, bootable Linux CD distribution ("LiveCD") for system administrators, based on Debian testing. You can mount and manipulate hard drives and partitions, monitor networks, rebuild boot records, install other operating systems, and much more. Finnix includes the latest technology for system administrators, with Linux kernel 2.6, LVM2, encrypted partitions, etc. And above all, Finnix is small; currently the entire distribution is over 300MB, but is dynamically compressed into a bootable image under 100MB. Finnix is not intended for the average desktop user, and does not include any desktops, productivity tools, or sound support, in order to keep distribution size low.
Finnix is freely distributable under the terms of the GNU General Public License.
