Package: libnss-mdns
Version: 0.14.1-1
Severity: normal
Tags: ipv6

After upgrading my laptop from stretch to buster, I'm not able to mount NFS via
mdns.  I have the following entry in /etc/fstab:

  vanvanmojo.local:/mnt/storage   /mnt/storage         nfs4       noauto,nofail,x-systemd.automount,x-systemd.mount-timeout=10,x-systemd.requires=network-online.target,x-systemd.idle-timeout=10m        0       0

The mount fails with the following log message:

  stgulik kernel: [  575.329441] NFS: bad IP address specified: addr=2606:6000:4502:1d00:4639:c4ff:fe53:e49b%2

It looks like the scope id was added in #644912.  This may be a kernel bug if
the scope id should be accepted.

Thanks,
Ross
