I don't have too much of a personal bias against it - it's mostly that a lot

In the SME Server, we have an init.d/daemontools script which we link
all other init.d/thing scripts to - at last count, over 20 links to the
same startup script. We then link rcX.d/Sxxthing to ../init.d/thing in
the usual way and everything looks "normal".
I've attached it, in case you might find it useful.
Thanks,
