Bug#872703: system.conf.d include directories are ignored

[Jonas Meurer]

Package: systemd
Version: 232-25+deb9u1
Severity: normal

Hello,

apparently, the system.conf.d include directories as mentioned in
systemd-system.conf(5) manpage are not considered by the systemd daemon.

When trying to set a global environment variable using the
DefaultEnvironment directive, I discovered that it is only recognized
when set in /etc/systemd/system.conf. If I put it into an include file
at either of /etc/systemd/system.conf.d/, /lib/systemd/system.conf.d/ or
/run/systemd/system.conf.d/ it's not recognized:

# systemctl show-environment
LANG=en_US.UTF-8
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
# echo 'DefaultEnvironment="VAR1=val1"'
>/etc/systemd/system.conf.d/test.conf
# systemctl daemon-reexec
# systemctl show-environment
LANG=en_US.UTF-8
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
# echo 'DefaultEnvironment="VAR1=val1"' >>/etc/systemd/system.conf
# systemctl daemon-reexec
# systemctl show-environment
LANG=en_US.UTF-8
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
VAR1=val1

I tested this on Debian Jessie with systemd 215-17 and on Stretch with
systemd 232-25+deb9u1.

Cheers,
 jonas
