Not where it involves *critical* files:

OPTIONS
-R libexecdir
This option is only available if Apache was
built with the SHARED_CORE rule enabled which
forces the Apache core code to be placed into
a dynamic shared object (DSO) file. This file
is searched in a hardcoded path under Server-
Root per default. Use this option if you want
to override it.

True, but then that negates the whole argument about not having a command
line option, no? Which I believe was the whole argument on this ... no?

God, I wish I had thought to note it at the time ... one of the things I
did when I dove into this was to check how various Unix daemons were doing
it, now I can't recall which I was looking at that mentioned the config
file overriding the command line options, but you are correct, the command
line should override the conf file ...
