The user can select an NTFS directory as the Project directory, even though Linux can not be customized on an NTFS partition.

The user should not be able to select an NTFS directory on the start page.

Cubic should display an error message and not allow the user to proceed to the next page: "Error. Cannot customize Linux on the NTFS file system.".

Assumption: Also FAT* file systems will most probably refuse file names with colons.

Good point.

We can include that.

I couldn't find a practical list of file systems.
I think "FAT*" shows up as "VFAT" in Linux?
I'm not sure if the Linux `df -T` will display "FAT32" as a type?

Let me know if you know otherwise?

Cubic will explicitly check for the following file systems on the Start page:

    - FAT
    - FAT16
    - FAT32
    - NTFS
    - VFAT

(There may be other file systems that present similar file name limitations as FAT or NTFS, but the above list should cover the most common use cases).

The following error message will be displayed below the Project Directory Entry filed.

    "Error. Cannot customize Linux on the <FILE SYSTEM TYPE> file system."

The Next button will be disabled until the user selects a directory that is not on a partition using one of the above file system types.

Fix released in version 2020.09-32-release.
