Re: [clamav-users] Using clamd@ service vs launching clamd from command line

[neel roy via clamav-users]

Thanks. 

On selinux, which is the case with me, running clamd as *standalone process* is 
more advantageous than running as systemd service. The reason is mentioned in 
the post by someone else couple of years back. I am facing similar 
issue: https://github.com/Cisco-Talos/clamav/issues/582

In case of systemd process, clamd can have graceful exit using "systemd 
stop clamd@scan" but same can be achieved by "kill -TERM <pid of 
clamd>" if clamd is running as standalone executable.

So given a choice, what would be reason why a user would want to run clamd@ 
service (instead of standalone process)?

Thanks in advance,
-Neel.

I'd say clamd service runs clamd.
the "service" is just systemd way to run it.
