--- Begin Message ---
Hi folks,
BRIEF
* I have NetDisco running on an old CentOS 7.9 box; I have built a new
Rocky 9.3 and am attempting to install NetDisco there
* I have followed the install instructions:
https://metacpan.org/pod/App::Netdisco
* When I reboot the box, I see the following in syslog - what step might I
have missed during installation?
