FEBRUARY 22, 2018

Prior to SQL Server 2017 CU4 for Linux (Linux only) the generation of a sequential UUID may not function as expected. SQL Server’s NewSequentialId () calls the Windows API UuidCreateSequential , which is limited in SQLPAL, prior to the CU 4 update. SQL Server on Linux – CU4 advances the logic in the SQLPAL, in support of UuidCreateSequential, adding a pseudo-mac, random increment, boot id and persisting the value in the /var/opt/mssql/.secrets/instance_id file.
