OK, but the trace above is =E2=80=9Cas expected=E2=80=9D, isn=E2=80=99t it? > "(getpgid ") returns 0, and calling "(kill 0 SIGTERM)" > kills all processes. What made you think of this scenario? I don=E2=80=99t think getpgid(2) can return 0. Or am I missing something? Since guix-dameon doesn=E2=80=99t actually daemonize, getpgid(pid) =3D pid. Running this (in a VM) works fine: while herd set-http-proxy guix-daemon foo ; do : ; done Thanks for debugging! Ludo=E2=80=99.
