Package: pppconfig
Version: 2.3.22
Severity: important

Dear Maintainer,

in the Journal occurs following error message of the dns-clean.service each time the PC.

# systemctl status dns-clean.service
● dns-clean.service - Clean up any mess left by 0dns-up
Loaded: loaded (/lib/systemd/system/dns-clean.service; enabled; vendor preset: enabled)

Jun 01 20:49:51 snowcat systemd[1]: dns-clean.service: Failed with result 'exit-code'.

The service file dns-clean.service from the /lib/systemd/system has the following contents.

[Unit]
Description=Clean up any mess left by 0dns-up
DefaultDependencies=false
Before=network-manager.service systemd-networkd.service networking.service resolvconf.service
After=local-fs.target
Requires=local-fs.target
ConditionPathExists=/etc/ppp/ip-down.d/0dns-down
[Service]
Type=oneshot
ExecStartPre=/bin/mkdir /var/run/pppconfig
ExecStart=/etc/ppp/ip-down.d/0dns-down "0dns-clean"
[Install]
WantedBy=multi-user.target

The line with the statement "ExecStartPre" causes my opinion the error because the directory /var/run/pppconfig will probably
never expire and is always present when booting the system.

The error is reproducible at any time. If I can still information is needed on my system to provide this.

Regards
Michael Singer

Could any of you try this instead and tell us if the problem goes away?

ExecStartPre=/bin/mkdir -p /var/run/pppconfig

(I don't maintain pppconfig, I just made the last QA upload,
but this error seems definitely easy to fix).

Thanks.
