This is exactly my point with one difference: as the documentation has
implied ("it runs (nearly) last"), I have always thought of rc.local as a
script where to put commands that could be run generally for all or some
users when the boot sequence is finished and the system ready
(typically commands that users will type first and always after logging in).
At least, as implied by the documentation, it should run last.
For whatever depends of the time to be launched, the infrastructure is
rc.d (or whatever directory added to rc_directories) since, as you
write, all the places in the boot sequence are valid ones.
It is definitively not a technical problem: the rc.d structure
allows to solve my problem (as well as others'). It is more a lack of
consistency. rc.local is a convenience for putting miscellaneous
commands system wide when the system is ready (at least that is what the
documentation has always implied for me).
