Good afternoon; Installing sendmail package as: (packages (cons* nss-certs ;for HTTPS access ; (several other packages here) sendmail %base-packages)) Results in sendmail installing in this location: /gnu/store/b0gmd1ac6np7zgb8hvbfgy45b0haz8xg-sendmail-8.15.2/usr/sbin/sendmail But no links for sendmail show up under any user's profile, and asking on #guix seems to indicate that sendmail should install under /usr/bin, not /usr/sbin which may be the issue. Thank you, -- Brant Gardner
