On CentOS Stream 9 systems, the isobuilder tool currently fails because it depends on the isoinfo command, which is no longer provided by any package in the CentOS 9 standard repositories.
In previous CentOS versions, isoinfo came from the genisoimage or cdrkit packages, but these are no longer maintained or available in CentOS 9. As a result, fresh CentOS 9 installs cannot satisfy this dependency, breaking isobuilder workflows.

    Always

    1. Install a fresh CentOS Stream 9 machine.
    2. Run isoinfo.
    3. Observe failure or errors due to missing isoinfo.

ISOBuilder script fails at runtime when it tries to invoke isoinfo, which is unavailable on CentOS 9.

[test@zt-triton-01 agent-installer-utils]$ isoinfo
bash: isoinfo: command not found... 

OVE ISOBuilder fails because isoinfo: command not found.

    OVE ISOBuilder should run successfully. 

Refactor isobuilder to replace isoinfo calls with xorriso or other supported tools
