Why is this:
$ df -h /
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on
/dev/disk1s5 234Gi 10Gi 15Gi 41% 482117 2448643243 0% /
Very different from this:
$ df -h .
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on
/dev/disk1s1 234Gi 205Gi 15Gi 94% 1911870 2447213490 0% /System/Volumes/Data
Is there an explanation with this new "data" filesystem? How is it different?
