For ipv4, I think applications using FQDN with "dnsdomainname",
"hostname -f" will still need custom /etc/hosts. I doesn't find a way
to provide (compatible with those softs) FQDN to nss-myhostname and
systemd definition of hostname (understand without dots in
/etc/hostname).

For ipv6, despite a negative comment in code[1], reverse seems to get
hostname and not localhost6.
# getent hosts ::1
