Thanks to hints from Renaud, I updated my Debian init script for nessusd
to take advantage of the distribution's own init structure.
You can find the updated script at:
http://andrew.org/hacks/nessus/debian-init/nessusd
As usual, copy this script into /etc/init.d, make it mode 755, user
root. You can then use the standard tools to include this script in your
startup sequence (update-rc.d(8) for details).
xpost goes to the current (?) nessusd package maintainer since it does
not seem to feature such script, at least according to what
packages.debian.org says.
