> On 23 October 2005, Finnix 86.0 was released. Earlier unreleased versions (84, and 85.0 through 85.3) were "Knoppix remasters", with support for Linux LVM and dm-crypt being the main reason for creation. However, 86.0 was a departure from Knoppix, and was derived directly from the Debian "testing" tree.[7]

My reading of this is that early versions of Finnix were based on Knoppix. However, according to the wikipedia sidebars, the initial release of Knoppix was 30 September 2000, while the initial release of Finnix was March 22, 2000. Something something beta/pre-release versions?
