Just want to use an exFat formatted USB stick with NR 21.04, and it became not readable.

I just take a look at `cat /proc/filesystems` and it shows no exfat support. Next up I try to use `sudo modprobe exfat` and then look again with `cat /proc/filesystems`

Now eFax is shown in the list and my USB stick is readable. Looks like a bug?

The default would be using exfat-fuse package and debian aswell as we default to this as the builtin kernel one might be a bit old (though yeah backports kernel should have a more recent more stable version)
