I would strongly discourage the use of profiles in users=E2=80=99 home directories. When introducing Guix we now only demo =E2=80=9Cguix shell=E2= =80=9D, which is preferrable in most cases. =E2=80=9Cguix gc=E2=80=9D is problematic whe= n profile links are in locations that the daemon cannot read.=20 > Efraim suggested using a shared daemon ssh-ing GUIX_DAEMON_SOCKET.

We only export /var/guix/profiles, not anything else in /var/guix. Using GUIX_DAEMON_SOCKET with a network port (make =E2=80=9Cguix-daemon=E2= =80=9D listen on that port) is all we ever needed. --=20 Ricardo Wurmus System administrator BIMSB - Scientific Bioinformatics Platform Max Delbrueck Center for Molecular Medicine email: ricardo.wurmus@mdc-berlin.de tel: +49 30 9406 1796
