Why does DistroWatch include BSDs and Solaris?
Originally, the site covered Linux distributions only. However, after numerous requests from readers, BSDs and BSD-based projects were added to DistroWatch in May 2004. The reasoning behind this move was simple – Linux and BSDs have much in common – both are free and open source operating systems, and they both use many of the same open source packages available on the Internet. Best of all, the various BSD flavours are widely used and considered by many to be great operating systems. Similarly, Sun Microsystem’s Solaris was frequently requested to be included in DistroWatch, especially after the release of version 10 with a much less restrictive license than their previous releases. However, Solaris is listed here purely for reference purposes and not as an endorsement of the product.
