    When opening a new session sudo tries to resolve the fqdn of the host, but that
introduces a sensible delay if the host does not have a fqdn set up
appropriately, as it is often the case with development board or when booting
images in QEMU.

We currently also ship libnss-myhostname which in theory could solve the issue
at the system level and not just for sudo, but upstream configures it to come
*after* dns resolution to avoid breaking `hostname --fqdn`, see
https://github.com/systemd/systemd/issues/1280



Our use-case is sligthly different and we may configure libnss-myhostname to
precede dns resolution, but in the meantime keep disabling this in sudo as the
apertis-customization package used to do.

# FQDN lookup is painfully slow if the DNS server is misconfigured.
