[Pkg-clamav-devel] Bug#804132: clamav-daemon: cannot create PID file while running under systemd

[Sven Hartge]

Package: clamav-daemon
Version: 0.98.7+dfsg-0+deb8u1
Severity: normal

Hi!

While running under systemd, clamd cannot create its PID file because
the directory /run/clamav/ does not allow the clamav user to create files.

The SysV-Init script chowns this directory before clamd is started but the
systemd unit does not do this, resulting in the following error on every
start:

Nov  4 16:31:24 XYZ clamd[655]: ERROR: Can't save PID in file /var/run/clamav/clamd.pid
Nov  4 16:31:08 XZY freshclam[589]: ERROR: Can't save PID to file /var/run/clamav/freshclam.pid: Permission denied

The daemon runs fine and does not seem bothered by this error, but other
tools looking for the PID file may throw an error. Also this shows up
on any logscanning tool looking for anomalies in the syslogs.

The fix seems simple, a little ExecPreStart like this should do:

| # /etc/systemd/system/clamav-daemon.service.d/chown.conf
| [Service]
| ExecStartPre=/bin/mkdir -p /run/clamav ; /bin/chown clamav /run/clamav

The same error applies also to the clamav-freshclam package.

Grüße
