This happens during bootup of my machine: * Starting pdnsd ... [ ok ] * Starting pdnsd-online ... Error: could not open socket /var/cache/pdnsd/pdnsd.status: No such file or directory [ !! ] It seems like pdnsd needs a short moment to create the socket so this is a typical race condition. In my case, the machine is an ancient 550 MHz Pentium-3. I didn't measure exactly but the socket file gets created about two seconds after /etc/init.d/pdnsd was started successfully and during these two seconds, /etc/init.d/pdnsd-online gets started and fails with the above mentioned error.

Created attachment 174356 [details, diff] pdnsd.online.diff How about this possible fix? I introduced a new function wait_for_socket() which checks every second if the socket exists. I set the default timeout to ten seconds which should be enough even for very ancient systems.
whoops, chose wrong component.
Your patch looks good, but it contains some bash-isms in it. Better solve this things, for the sake of portability: - don't use [[ ]], use simple brakets - "until" keyword doesn't seem to be present in the POSIX manual page of the sh command my personal choice: for ((i=0; $i < 10; i=$i+1)); do [ -S ... ] && return 0 sleep 1s done
Created attachment 175005 [details, diff] pdnsd.online.diff You are abolutely right. I completely forgot that bashisms are no longer a good decision when writing init-scripts which might be used with openrc... How about this patch where I tried to incorporate your suggestions?
Fixed in cvs. Thanks!
