What support are you looking for? SQL Server on Linux, is for the most part, SQL Server. Django support for SQL Server should be roughly the same on Windows and Linux, they're just client apps.

All my testing, which is inherently limited to the things I look at, show that apps seamlessly port over from Windows to Linux, unless they're doing something in the file system, or have complexities with SQL Agent and other subsystems. Maybe of the Agent limitations have been removed, I just haven't retested.

MS supports Linux the same as Windows, with lots of their systems people having spent the last year+ learning about the differences between Windows and Linux.

Are they all going to be experts on client interactions? No, but they should be able to provide support in most cases.
