Auto-mount encrypted drive for multiple user accounts

Is it necessary to put the user’s home directory on the drive? Can you put the home directory on the internal drive and then create a folder on the external drive owned by that user, which can hold all of its documents and databases?

Yes, putting Home on the internal is fine as long as the navigating to the data is transparent, i.e., clicking on the folders within Home automatically map to the data on the external drive.

Ideally, I’d like to change all these standard folders at the root of Home into symlinks to a corresponding folder on the external drive:

1. Desktop
2. Documents
3. Library
4. Movies
5. Music
6. Pictures
7. Public

(The part of ~/Library that concerns me ~/Library/CloudStorage )

Is this possible?

1. Does macOS require them to to be UNIX directories?
2. Are symlinks limited to the same drive?
