This is a bug, basically.

You could try to work around it by creating a file
/usr/lib/guestfs/supermin.d/00-dir containing the following lines:

----------------------------------------------------------------------
/
/mnt
/mnt/bigdata
/mnt/bigdata/var
----------------------------------------------------------------------

(not including the dashes).

If that doesn't work, take the supermin-helper command that is printed
in the debug output, and try adding -v -v -v to the command.  That
should make it print plenty of debug.  For example
libguestfs-test-tool prints:

  libguestfs: command: run: /usr/bin/supermin-helper
  libguestfs: command: run: \ --verbose
  libguestfs: command: run: \ --copy-kernel
  libguestfs: command: run: \ -f ext2
  libguestfs: command: run: \ --host-cpu x86_64
  libguestfs: command: run: \ /usr/lib64/guestfs/supermin.d
  libguestfs: command: run: \ --output-kernel /var/tmp/guestfs.pGpWYN/kernel
  libguestfs: command: run: \ --output-initrd /var/tmp/guestfs.pGpWYN/initrd
  libguestfs: command: run: \ --output-appliance /var/tmp/guestfs.pGpWYN/root

I run:

  supermin-helper -v -v -v --verbose --copy-kernel -f ext2 --host-cpu x86_64 /usr/lib64/guestfs/supermin.d /tmp/kernel --output-kernel /tmp/kernel --output-initrd /tmp/initrd --output-appliance /tmp/appliance
