If you had fun with Slackware (Salix OS in this case), you could give it a
chance to Freenix (formerly known as Freeslack) which is a Free eXpansion
Pack for Slackware. This means that you install a vanilla Slackware and once
the installation process is finished modify your repositories to Freenix so
that it replaces and removes the non-free software and kernel. This project
is basically focused on listing and removing all non-free applications
included in the software installation disk so it is not a GNU/Linux
distribution itself.
Beyond that they do not make any additional modifications, as is typical in
the Slackware community, they respect and greatly value the decisions that
their benevolent dictator for life, Patrick V. in this case, considers for
the distribution.
I tried it a long time ago and I have a lot of love and respect for this
project. The only warning I can give you when using a Slackware-Libre is to
be careful when using or installing any application from the Slackbuilds
community repository, something similar to the Ubuntu's ppa, since, they do
not have such a firm conviction about the ideology of the FSF as the truly
libre distributions.
I assure you you'll have a lot of fun with Slackware-Libre.
Best regards.
