However, what about freedom (1) and (3) (freedom to [...] a= nd > change the program in source form and (3) distribute modified versions)? Each license is free [1]. Therefore, they respect all the freedoms. The issue is about linking the result and distribute the binary. 1: > (*) raid5atemyhomework noted that guix does _not_ distribute source code, > it only points to source code locations.

Indeed, ci.guix.gnu.org keeps a copy of (as much as possible) source code. But ci.guix.gnu.org does not distribute all the corresponding binaries: see 'arguments' '#:substitutable? #f'. It is already the case for the package 'zfs': --8<---------------cut here---------------start------------->8--- (arguments `(;; The ZFS kernel module should not be downloaded since the license ;; terms don't allow for distributing it, only building it locally. #:substitutable? #f --8<---------------cut here---------------end--------------->8--- As explained in the initial submission [2], this patch set is just a "glue" usable by the user locally. No binaries on the Guix side is involved. All the source-code is under free license. 2: Cheers, simon
