Clamav freshclam fails when /var/log/clamav/freshclam.log does not exist #1155
Description
Describe the bug
When /var/log/clamav/freshclam.log does not exist (such as when /var/log is mounted as tmpfs to extend SSD (or SD card on rpis) longevity), freshclam does not create the log file and simply crashes (the systemd freshclam service).
How to reproduce the problem
- Mount
/var/log/astmpfs. - Reboot
- Start
clamav-freshclam.service
