[pkg-gnupg-maint] Bug#852697: gnupg-agent: automatically starts gpg-agent in root user slice

[Laurent Bonnaud]

Package: gnupg-agent
Version: 2.1.18-3
Severity: normal


Dear Maintainer,

I usually remotely log in (via ssh) as root on a system where gnupg packages are installed and I noticed that a gpg-agent process is created for the root user:

# systemd-cgls
Control group /:
-.slice
├─user.slice
│ └─user-0.slice
│   ├─user at 0.service
│   │ ├─dbus.service
│   │ │ └─16957 /usr/bin/dbus-daemon --session --address=systemd: --nofork --nopidfile --systemd-activation --syslo
│   │ ├─gpg-agent.service
│   │ │ └─15353 /usr/bin/gpg-agent --supervised
│   │ ├─init.scope
│   │ │ ├─31495 /lib/systemd/systemd --user
│   │ │ └─31497 (sd-pam)
│   │ └─gvfs-daemon.service
│   │   ├─17040 /usr/lib/gvfs/gvfsd
│   │   └─17045 /usr/lib/gvfs/gvfsd-fuse /run/user/0/gvfs -f -o big_writes

This process is of no use to the root user and therefore the system would be better without it.  Would it be possible to prevent the creation of this process?
