It depends what the file =E2=80=99path/to/channels-wo-guixrus.scm=E2=80=99 = would contain. :-) My point was just to say that this speculative =E2=80=9Cignore-channels=E2= =80=9D could already be emulated using =E2=80=9Cguix time-machine=E2=80=9D. From my und= erstanding of what this speculative =E2=80=9Cignore-channels=E2=80=9D would do. BTW, please note that this operation =E2=80=9Cignore-channel=E2=80=9D would= be costly because at least one =E2=80=9CComputing Guix derivation=E2=80=9D is require= d. Cheers, simon
