None that I can think of, actually.  The only issue that bothers
me somewhat is that the above might miss an /etc/rc.conf.local;
however, if /etc/defaults/rc.conf does not have source_rc_confs_defined,
then we are clearly not on any reasonably recent FreeBSD system,
so I don't know whether any assumptions should be made about the
existence and relevance of /etc/rc.conf.local.  On any reasonably
recent FreeBSD system with rcOG, source_rc_confs_defined would be
defined, and source_rc_confs() should take care of all the conf files.

G'luck,
Peter
