Control: tags 1031236 + pending Dear maintainer,
I've prepared an NMU for ifupdown (versioned as 0.8.41+nmu1) and intend to upload it to DELAYED/10 once I properly tested the patch. (Unfortunately I locked myself out of the affected machine while reconfiguring the network devices. So testing will have to wait until I find someone with physical access to that machine.) The change is effectively what Ken Milmore proposed. Best regards Uwe
