>MSSQL also runs on a abstraction layer since v2005 so there's no inherent problem with running on Linux.

Yes, one would think an extra abstraction layer would render platforms exactly equal but that's not the real-world outcome. For example, Windows Server also runs on an "abstraction layer" called HAL (Hardware Abstraction Layer) and yet we had production problems with Windows on Itanium that had specific knowledge base articles and hotfixes for Itanium.

Did Microsoft premier support help us with Itanium problems?!? Yes, they were responsive and eventually solved some obscure bugs. But their support for Intel x86 was more complete and up-to-date. Likewise, I anticipate that Microsoft will be competent and helpful with customers running SQL Server on Linux. But I don't expect their specialists to have the same level of expertise as MSSQL on Windows.

If someone wants to run MS SQL Server on Linux, that's fine but don't think the enterprise platforms are equal. That usually doesn't turn out to be the case.

>Also containers change the entire scenario.

I'd be totally comfortable with MSSQL on Linux for dev/sandbox/QA environments (avoids licensing costs of Windows). But not for mission-critical production deployment.
