antiX kernels are built directly from source.
We do not ‘deblob’ anything (unlike Debian) so I guess it will have some non-free elements.
I might be wrong on this though.
Not a problem, there’s lots of deblobbed kernels available. Developer Jason Self from the Trisquel project makes a Linux-libre kernel repo available for all Debian based distros, I’ll probably use that for now. It’s useful in that it gives users the options of going with the latest kernel, or the latest LTS, or the 4.19, 4.14, 4.9, or 4.4 LTS kernels, similar to many of the kernel options that users normally get with antiX: https://jxself.org/linux-libre/
