A brief incursion into clamav-0.85-r1 shows that, as commented in the /etc/conf.d/clamd file, that all parameters now are ignored except for START_CLAMD and START_FRESHCLAM. This means that FRESHCLAM_OPTS is also being ignored, and the "-d" is not being passed to freshclam to daemonize the process. Is another method being used to start this process?
Yes, I'm sorry for that - I forgot to move the "-d" from conf.d file to the new initscript. Anyway, if you resync now and remerge 0.85-r1, the initscript will be updated, as I've fixed this already yesterday.
