the point is that there is a bug in NUT, and I dislike when I don't
I've tracked it, for later processing:

this one is indirectly tracked through the above bug ticket.

Don't worry about the lag, and thank you for the hard work (and more)!

for the sake of completion, part of the more, I'm also local councilor and
leaving in the mountain.
we just got our first snows of the year this week-end. 20 cm is not that
much, but already making an overhead of work...
