Upstream thus recommends to ship as + # many of them as possible. There is however a problem: + # inspircd is licensed under the GPL version 2 only and + # some modules link libraries that are incompatible with + # the GPL 2. Therefore we can't provide them as binaries + # via our binary-caches, but users should still be able + # to override this package and build the incompatible + # modules themselves. + # + # This means for us we need to a) prevent hydra from + # building a module set with a GPL incompatibility + # and b) dynamically figure out the largest possible + # set of modules to use depending on stdenv, because + # the used libc needs to be compatible as well. + # + # For an overview of all modules and their licensing + # situation, see https://docs.inspircd.org/packaging/ + + # Predicate for checking license compatibility with + # GPLv2.
