FreeSlack is a Free eXpansion Pack for Slackware. The project's primary goals are to document all non-free software in Slackware distribution, and to make it easy for users to maintain a fully free OS based on Slackware.
Technically speaking, FreeSlack is a complete distribution and a Slackware derivative, but we prefer to think of ourselves as a shortcut to a free flavor of Slackware. We are not affiliated with the Slackware project, have no developers in common, and share no infrastructure. We use the term Slackware only in reference to the stock OS distributed by Patrick Volkerding. One of our ambitions is to become integrated within the existing Slackware community, and we hope to achieve that by making the smallest possible changes needed to deblob Slackware, while leaving all technical decisions up to the Slackware team.
Attention! While it is our intention to support the releases at least as long as they are supported upstream, we would like to explore the possibility of retiring 14.1 early, simply because we believe it has zero users (aside from a few volunteers who keep it around for quality control purposes). Please let us know if you are planning on using 14.1 in production a while longer. Unless we hear from you, we are likely to end support for 14.1 by 2018.
If you are looking for a 32 bit OS, check out ConnochaetOS, a free and libre GNU/Linux distribution for x86 computers with limited resources, based on Slackware and Salix OS.
