This is a strange one. I'm running Ubuntu 20.04, and freshclam doesn't seem to like it when you try to point it at any config file other than what is default.

I ran the dpkg-reconfigure clamav-freshclam command to create the default /etc/clamav/fresh.conf file. So freshclam is working fine. I'm explicitly passing the --config-file option to show this works.

This is where things get weird. I copy the default freshclam.conf file to another location, and it then doesn't work. What's going on here?
# ls -la /etc/clamav/freshclam.conf
-r--r--r-- 1 clamav adm 593 Jun 23 16:00 /etc/clamav/freshclam.conf
# cp -av /etc/clamav/freshclam.conf /etc/
'/etc/clamav/freshclam.conf' -> '/etc/freshclam.conf'
# ls -la /etc/freshclam.conf
-r--r--r-- 1 clamav adm 593 Jun 23 16:00 /etc/freshclam.conf
# freshclam --config-file /etc/freshclam.conf
ERROR: Can't open/parse the config file /etc/freshclam.conf
Adding -v doesn't change this output. I'm stumped! Actually, if I rename the default /etc/clamav/freshclam.conf to anything else, freshclam won't read it. Ehhh.
I also want to change the DatabaseDirectory to an nfs location, but that doesn't seem to work either. This seems very strange. Anyone else able to replicate this?
