Hi!
It's been a long time since this bug entered the system, and now I have a
patch for it, I have to say it is a little dirty (I'm just adding the bridge
back on the stances that had it removed before them) so that way they won't
fail when trying to remove it.
This will work if you do:
ln -s /lib/bridge-utils/ifupdown.sh /etc/network/if-down.d/bridge
and apply the attached patch.
I'd love to see comments on this, even though more than 15 years later...
well who knows.
Whis patch is a little big, so I don't know if it will make it to Bullseye
at this time of the freeze :-( so all the testing will be welcome and will
of course help get it on Bullseye.
Regards....
