Samba will work, but without this it cannot update it's own DNS
records.

The script samba_dnsupdate calls out to the system binary 'nsupdate' to
do the actual work here.  

This is the fine line between re-using code and the simplicity that
comes from (re)implementing the functionality internally to Samba.  For
this and other reasons it seems clear that we will move to an internal
implementation of the features nsupdate provides in the future.
