>Description:

        The setting of rtsold_flags in /etc/defaults/rc.conf as empty,
        without any interfaces to configure, causes rtsold(8) to fail.
        Cf. rtsol_flags, which is set to `-a' in order to make rtsol(8)
        try all interfaces.  It would be nice if rtsol(8) and rtsold(8)
        worked by default, or at least compatibly, just by setting
        rtsol=YES and rtsold=YES in /etc/rc.conf.

>How-To-Repeat:

        Set rtsold=YES in /etc/rc.conf, but not rtsold_flags.  Run
        /etc/rc.d/rtsold.

>Fix:

        To make rtsol(8) and rtsold(8) work by default, the default
        setting of rtsold_flags should probably be `-a'.

        Alternatively, rtsol_flags could be set to empty, and both
        /etc/rc.d/network and /etc/rc.d/rtsold could have precommands
        that require the flags to be non-empty (to approximate the
        actual requirement).  In this case, the rc.conf(5) man page
        should mention that setting rtsol=YES and rtsold=YES requires
        also setting rtsol_flags and rtsold_flags to specify the
        interfaces to autoconfigure.
