Hi,
in my use-case urndis is likely never there at boot, and while i've
been aware of ifstated(8) all the time, the relevant man pages have
felt dry w/regards giving something trivial/!carp, to make me skip
setting this up again for far too long:)
/etc/examples/ifstated.conf also supported my previous view,
that this wasn't the tool i was looking for.
english, and all that + manpage diff, so i'll show everything necessary
for the simple use-case, instead of trying to add bits here and there..
originally i intended to just make it clearer that the "For example:"
under "STATE DEFINITIONS" was not about:
"It is also possible to write multiple nested if blocks.",
and iirc. in my quick testing i found out i actually needed the nesting
below in the auto state, to allow auto->running when starting ifstated
while urndis0 is already set up&working.
