The simplest (although there are many other ways to d this, not all are as easily self documenting or simple to use) is something like: /etc/default/package: # Configure here your options for each running daemon: DAEMON_1_OPTS="..." DAEMON_2_OPTS="..." DAEMON_3_OPTS="..." #(don't use 'export foo=bar here', just regular variable assignments) /etc/init.d/package: if [ -f /etc/default/package ] . /etc/default/package fi # This cuts any line that is only whitespace, or first non-whitespace # character is a comment (#), and parses the rest. DAEMON_OPTS_LIST=`egrep -v '^[[:space:]]*(#|$)' /etc/default/package \ | awk -F '=' '{print $1}'` for DAEMON_OPTS in "$DAEMON_OPTS_LIST"; do start-stop-daemon --start --quiet --pidfile /var/run/$NAME.$i.pid \ --exec $DAEMON -- $DAEMON_OPTS done or something. That would be user configurable and relatively discoverable. There are many other bash constructs that do this more efficiently, but you should try to keep the /etc/default file as straightforward as possible. I am still not sure I am addressing your question fully, but I think so. I think you want: single daemon, possibility of running multiple instances said daemon does not by itself run multiple instances by default (unlike, e.g, apache) said daemon should have different options on different instances I think my proposal allows that to happen, and in a user configurable way. If that is still not quite what you're looking for, write back - I'm sure we can dig something else up. -- ----------------------------------------------------------------- | ,''`.
