The requirement is to put logs into directories other than /var/log.
Could it be achieved by modifying the syslog daemon configuration file (e.g. /etc/syslog.conf) to replace /var/log with the specified directory. Maybe the corresponding logrotate configuration file also needs to be modified.

Best Regards,
Chen Qi

This variable is only respected when VOLATILE_LOG_DIR is "no".

The default value is "" which results in the /var/log being log directory.

The user could override this value to a path e.g "/home/root/log" which
results /var/log being a link pointing to /home/root/log directory on
persistent storage.
