Fix get_if_var() with 3 args (i.e. with default)
All xxx_<ifname> flags are set to empty strings automatically earlier so
eval echo \${${prefix}${_if}${suffix}-${_default}}
not substitute the default but return just the empty string.
Fix it using
eval echo \${${prefix}${_if}${suffix}:-${_default}}
(i.e. treat empty strings as unset)
The bug manifistates itself with the following warning from checkyesno():
/etc/rc.d/dhclient: WARNING: $background_dhclient is not set properly -
see rc.conf(5)
