The solution for that would be to:
	- rcorder the /etc/rc.d scripts
	- execute the scripts up to mountcritlocal and a dummy script
	  that has a "PROVIDE: MOUNTCRITLOCAL" or similar
	- rerun rcorder on the complete script list (including the
	  locals)
	- execute the list again, this time skipping over any in
	  /etc/rc.d before the MOUNTCRITLOCAL is reached (since they
	  were done before)

I don't know if that's getting too complicated.  I have to say I
prefer to keep things simple.

I also looked at /etc/rc.subr:run_rc_script and discovered that it
handles "foo" and "foo.sh" differently.  "foo", if executable, is run
in a subshell, whereas "foo.sh" is sourced into the current shell.
I suspect we don't want all the local rc foo.sh scripts sourcing into
the /etc/rc shell.  I.e., to make a change like this, all local rc
scripts would need to be renamed as well as having rcorder tags
added if not already there.

I currently use the hack to localpkg which I originally suggested.
I needed it because several existing ports fail to start without it
and that change does fix the problem.
