Hi Phil,

Pre-LSB, we used rcS due to some people wanting to do strange stuff
like run services in chroots and the like, which required it starting
before.  But this wasn't great for the common case.

In 1.5, I fixed the LSB header to use standard runlevels.  Unless
dh_installinit isn't resetting the links automatically on upgrade, we
probably want to force deletion and recreation of the links?


Regards,
Roger
