Package: ifupdown
Version: 0.7.48.1
Severity: normal
Compared to the hurd link.defn for loopback, we see these
are inverted, meaning that you would only be able to configure
a loopback device that was _not_ named "lo" (unlikely to exist).
The result was that we'd update /run/network/ifstate for "lo"
but never actually do anything for up/down, as shown below:
