Amit Khandelwal has an update on SQL Server on Linux:
We are glad to announce that SQL Server 2022 is now available in preview mode for both Red Hat Enterprise Linux (RHEL) 9 and Ubuntu 22.04. For this preview, only Evaluation edition is available, which is limited to 180 days starting Thursday, July 27th, 2023.
In your Dev/Test environments, you may now take advantage of the most recent SQL Server 2022 improvements on both RHEL 9 and Ubuntu 22.04. Currently, production workloads on RHEL 9 and Ubuntu 22.04 are not supported by the SQL Server 2022 preview packages. You can run the production workloads for SQL Server 2022 on RHEL 8 and Ubuntu 22.04 and they are fully supported.
I’m going to wait until it’s actually available for real, not just in preview.
