df -h prints:

Filesystem      Size  Used Avail Use% Mounted on
/dev/root        59G  6.6G   50G  12% /
devtmpfs        1.8G     0  1.8G   0% /dev
tmpfs           2.0G     0  2.0G   0% /dev/shm
tmpfs           2.0G  9.0M  1.9G   1% /run
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           2.0G     0  2.0G   0% /sys/fs/cgroup

tmpfs           391M     0  391M   0% /run/user/1000

while ncdu / prints:

Total disk usage:   1.8 GiB  Apparent size:   1.8 GiB  Items: 176500

Why is one reporting 6.6+ GiB used while the other reports only 1.8 GiB?
