Sorry, I indeed left out important context, thus even I had difficulty
recalling the reason for my report now.  So:

I use /lib/init/init-d-script to provide an init script for the
corosync-qdevice daemon.  I have to set NAME="corosync-qdevice", because
the NAME variable is used in several informational messages as well
besides as the --name value for start-stop-daemon.  But then I have to
override the do_start_cmd() and do_stop_cmd() shell functions to use the
correct --name value (or not use one at all).  The other choice would be
letting the informational messages use the truncated name, which is
suboptimal in a different (and visible) way.

I imagine that having an optional COMM_NAME (pick any name) variable
would solve this nicely, if it was used in preference to NAME for the
--name option of start-stop-daemon if it was set, like

start-stop-daemon --name "${COMM_NAME:-$NAME}"

or maybe even (just an untested idea):

if [ -n "${COMM_NAME:=$NAME}" ]; then
   NAME_ARG="--name=$COMM_NAME"
else
   NAME_ARG=""
fi
[...]
start-stop-daemon [...] "$NAME_ARG" [...]
-- 
Thanks,
