I suspect that I may be opening a can of worms on this one as I see that
the 'embedded' option in the 'catalina.sh' doesn't have a '-security'
option.
I guess that the only sensible way to proceed is to try and mimic the
embedded functionality with a mapper type approach as used with the
standalone implementation.
If nobody hears from me within a week, send in the dogs.
