Any > ideas? One maybe bizare suggestion that comes to mind is to use a container created through the `guix system container` command. This would allow you to create a set of processes, that you could give access to specific parts of the host filesystem (using the --share and --expose options), and expose the host network to if you want to use services which access the network (only with this patch [1]). The more things you do through the container, the closer you are to having something work just on GuixSD. You might get to the point where you can even replace what you are using from Debian with Guix packages that just unpack some Debian packages to the store. Where this approach might fall down is usability, e.g. reconfiguring a container isn't possible yet, so you might have to restart it when you want to make changes, which might be problomatic if you are doing this through the ssh service in the container... 1: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=3D28128 --Sig_/WRB_RsPqf.lz0iy4C_pjxwM Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEEPonu50WOcg2XVOCyXiijOwuE9XcFAlmb/atfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDNF ODlFRUU3NDU4RTcyMEQ5NzU0RTBCMjVFMjhBMzNCMEI4NEY1NzcACgkQXiijOwuE 9XdsGQ//Rx5rs3zaQoVOmB/IxywaafdFIgJrL3aAjaF4Sv32HOtNxU/iHhhsn6XZ QE2d5OmQNJTg/WsOxpS9fsTJzMLn6L8ITcIFtfAEyEAlo9yCqkBA1CLJasbFc0nL eYpQ5zWg9kcCRW6qaYculviTsBBMdP3gkSJ7SOIWa5z+qvg80f51WLgz9dz7h06w fNaKzD/oahQ2ZwJeWvgDu9U1tUm91PjOw81p9ratq+VD9njq1t3eSqnC+s0ly7tv 5xslSo0DdijRGdYhYmfDb3uAjfiS/Gz9Q+csvPS1+lcQAwZGXeihOHhxNjXsAP3v UuDgzmlD0MRCCy2XLgf1n76/+yj5Dp5Dx5tl/kA8h/nSh86uAL+GmxP5UMc/fcH6 /z9M5zwRfFhUkdsXQ+dIeB7WqH8Gz+gOKhWhEbdGEeAO8jvStHFiqStjvDdS+NUf kEP9kHYsTpzmJxlBT8fCMmaCXBvKjtcd4GZ7eyHBziHkmgmqfsezY5TSc966JEKi ZsWdw2BfMu+7d51ahAAP6O0pTZJZPT3fKZjUV4WqOEPJ97ep5yUuGaTjkHEaIsuL ia92n8NHFIEbBYSpLp0planiInItF13NosBPapX/IWuBerdFpv2q05YGgDJl62Rx 9IrCJhY1zCo6eh4mujyQ1ZGso+FupU5up+m9s66QerHxAW+HZHo= =i0Fs -----END PGP SIGNATURE----- --Sig_/WRB_RsPqf.lz0iy4C_pjxwM--
