The canonical way to disable a SysV init script is to turn the SXX
symlinks into KXX symlinks.
You can use update-rc.d foo disable|enable nowadays for that.
See man update-rc.d.

A dh_installinit --no-enable could thus be implemented by generating
code to run
update-rc.d foo defaults
update-rc.d foo disable
