One question though: I suppose dependencies of these packages have to be maintained in the same channel right? Otherwise, if I rely on packages from guix distribution, they can be dropped or updated to an incompatible version at any moment. That scares me a little, because it could break my channel anytime, or am I mistaken? > > For bioinfo package variants also take a look at the guix-bimsb channel: > > https://github.com/BIMSBbioinfo/guix-bimsb > > (I should update the README to recommend using channels instead of > GUIX_PACKAGE_PATH=E2=80=A6) > Looks interesting for me!
