Seems, it is one of those magic bugs, which are fixed, but return back. 8)

One warning. If you plan to write the information read from sys/net
back to sys/net, be ready to surprises.
Particularly, setting "forward" (and "flush", and, probably, a few
of another entries) has side effects and saving them is undefined.
Moreover, essentially, the script, which scans all sys/ and would-be "saves"
its content is non-sense. It should touch only variables, which are safe
to touch and, hence, should not touch variables with sense not clear
to script's author (or even undocumented variables, which will be _always_
present and are supposed to be touched only by expert's request/advice
in well understood curcumstances.)
It is the reason why I am not bothered too much by attributes on "flush".
