Rocky Linux is a community enterprise operating system designed to be 100% bug-for-bug compatible with America's top enterprise Linux distribution now that its downstream partner has shifted direction. It is under intensive development by the community. Rocky Linux is led by Gregory Kurtzer, founder of the CentOS project.

Testing with it now - would like to suggest adding it to the OS pulldown in place of CentOS with a nifty custom icon!

Thank you, Arthur...

We wouldn't be able to make this change here, but you're welcome to post an enhancement request on the Bugtracker.

"in place of CentOS"? AFAIK CentOS has never been listed.

I can't speak for the devs, but as a rule we don't seem to include clone OS's in the list of available templates, so for example we never had CentOS and we never had Mint. In fact keeping track of the list of obscure and vanity Linux distros could be a full time job for someone.

If Rocky is supposed to be the same as Red Hat, like CentOS was, then choose the Red Hat template.
