Question: Does it fallback to /bin/cp when a flag is not supported? In other words, can I alias cp to xcp? #22

Hi @KSXGitHub,

No, it doesn't fall-back. I never really intended xcp to be a 1-for-1 replacement for cp, but as a sandbox for experimenting with UI and performance improvements.

It's also worth noting that there might be some problematic corner cases that xcp doesn't yet handle due to corresponding issues in the kernel with copy_file_range(); LWN has details: https://lwn.net/Articles/846403/ I have a outstanding task to implement testing of these, but the real world has been intruding recently.

Cheers, Steve
