I also followed the owncloud/btsync setup for the raspberry. I use the following autostart script to launch btsync: #! /bin/sh # /etc/init.d/btsync # # Carry out specific functions when asked to by the system case "$1" in start) start-stop-daemon -c www-data:www-data --start -x /home/pi/.btsync/btsync ;; stop) killall btsync ;; *) echo "Usage: /etc/init.d/btsync {start|stop}" exit 1 ;; esac exit 0 This starts the service as user www-data and group www-data, the executable is at /home/pi/.btsync/btsync It still doesn't preserve the permissions (somehow I'm getting 644), but it's close enough. Would be great if a default umask could be set somewhere. Right now I just have a cron-job keeping the permissions intact.
