${name}_flags
Arguments to call command with. This is usually set in
rc.conf(5), and not in the rc.d(8) script. The environment variable
`flags' can be used to override this.
That calls "command", it does not append a value to it. I receive an error
that "eval" cannot handle it.
I am going to try:
load_rc_config_var name var
Read the rc.conf(5) variable var for name and set in the current
shell, using load_rc_config in a sub-shell to prevent unwanted side
effects from other variable assignments.
