It translates to "be verbose about restoring factory settings", because
without arguments it will restore the built-in set.
The 'alias' shell command is suitable for user protection:
alias ldconfig='/sbin/ldconfig -r'
This will default to -r if called as ldconfig. If you really do want to
modify the search path on the command line, you can type the full path
to the ldconfig binary, as in: /sbin/ldconfig -vm /usr/local/lib.
Similar:
alias rm='rm -i'
alias cp='cp -i'

Problem with today's modular software: they start with the modules
and never get to the software part.
