The user facing guix command has two modes of failure as I have seen, when doing "guix upgrade" or "guix package -u":
1. if when downloading substitutes, if downloading fails due to network conditions, the whole command errors out (exits) 2. if some software has to be built locally, and if the build fails, the whole command errors out (exits) is it possible to have the guix command keeps going and finishes other works that may be unrelated to the failure, and finally prints out messages about the packages that failed to update? This would be more user friendly and makes guix more usable for end users. Thanks
