• Program: Authoritative pdnsutil
• Issue type: Bug report

Short description

pdnsutil replace-rrset seems to append the ZONE to the name argument, presumably to produce an absolute name, but it does this even if you give an absolute name (with trailing .).

Environment

• Operating system: Debian sid
• Software version: pdnsutil 4.8.3
• Software source: Debian sid repositories
• launch+=gsqlite3

Steps to reproduce

pdnsutil create-zone example.com # prerequisite
pdnsutil replace-rrset example.com. www.example.com. A 60 127.0.0.1

Expected behaviour

Current records for www.example.com IN A will be replaced
New rrset:
www.example.com. 60 IN A 127.0.0.1

Actual behaviour

Current records for www.example.com.example.com IN A will be replaced
New rrset:
www.example.com.example.com. 60 IN A 127.0.0.1

Other information

Discovered on PowerDNS auth 4.7.3 on Debian 12, double checked in a Debian sid container.
