pdnsutil replace-rrset should be improved

[tuxis-ie]

While trying to update the NS rrset for a zone, when using logical parameters on the commandline, you get unexpected results.

e.g.:

# pdnsutil list-zone prevented.nl | grep NS
prevented.nl	3600	IN	NS	nssecauth1.tuxis.net.
prevented.nl	3600	IN	NS	nssecauth2.tuxis.net.

I expect the following to work:

pdnsutil replace-rrset prevented.nl prevented.nl NS ns1.allcloud.nl ns2.allcloud.nl

But that results in:

# pdnsutil list-zone prevented.nl | grep NS
prevented.nl	3600	IN	NS	nssecauth1.tuxis.net.
prevented.nl	3600	IN	NS	nssecauth2.tuxis.net.
prevented.nl.prevented.nl	3600	IN	NS	ns1.allcloud.nl.
prevented.nl.prevented.nl	3600	IN	NS	ns2.allcloud.nl.

Adding a . to the NAME does not help, that creates NS records or prevented.nl.prevented.nl. . Using . as NAME does work, as does @.

While how this works isn't actually incorrect, it is kind of confusing and could do with some improvement.

IMO this isn't confusing but wrong, particularly as the same utility with the edit-zone subcommand clearly indicates that all names therein are ABSOLUTE! (emphasis not mine).

Looks like a duplicate to me.
