Catalina data partition?

Valued Contributor

Hi Folks,

When I use the installer through the GUI to install Catalina after first erasing the Macintosh HD partition and after installing and rebooting, there is a data partition. When logging in, the user folder is created onto this data partition.

When using the command line startosinstall commands via a script this doesn't happen. Does anyone know how to get this created using this command line?

I have checked out the usage examples, but I am not seeing flag or switch to use so we get this created.
