Command line options: copyup on MD change #8

Open kcgthb opened 5 years ago

kcgthb commented 5 years ago

Provide a command-line option to enable/disable copy up on metadata change.

MD changes (such as ower, timestamps, permissions) can be considered as modifications in the lower layer(s) and then initiate a copyup. Or they can be considered non-significant changes (as they don't modify the actual data) and only be carried upon in the lower levels.
