How do we go about installing a pre-release version of CentOS Stream 9 ?
Download an .iso and install it like any other release. They don't link to it on the front page but if you look around, you can find it. Here's a working link at the time of writing:
https://composes.stream.centos.org/production/latest-CentOS-Stream/compose/B...
Please note that once installed you can't use your package manager because the CS9 repositories haven't been setup yet... so if there is something you want to try, it's probably a good idea to select it at install time... although you can certainly mount the .iso image post install and manually install any of the rpms on the media.
TYL,
