Dyson

Actually, host utility and others are used for Debian-specific checks on local domain in avahi-daemon-check-dns.sh. These checks also involve ifconfig utility with linux-specific output format. So for Dyson is should be either ported or disdabled.

More over knot's host has different output, and can't be used with avahi that easy:

Knot:

# host -t soa local.
Host local. type SOA error: NXDOMAIN

Bind:

# host -t soa local.
Host local. not found: 3(NXDOMAIN)

Avahi:

  OUT=`LC_ALL=C host -t soa local. 2>&1`
  if [ $? -eq 0 ] ; then
    if echo "$OUT" | egrep -vq 'has no|not found'; then
      return 0
    fi
  else
