coreutils: mv discards extended attributes when moving to a different volume

[DanielSmedegaardBuus (Daniel Smedegaard Buus)]

Hello :)

The mv version included with coreutils in MacPorts (also Homebrew, just for reference) discards extended attributes when moving a file from one volume to another (not intra-volume). This doesn't happen with the OS X bundled mv, or with coreutils on Ubuntu that I tested on, too.

Sounds like not a MacPorts-specific problem that should be reported to the developers of coreutils. When they fix it and release a new version, we can of course update to that version in MacPorts.

Roger that :) I've written to the bugs-coreutils mailing list. I'll report back.

So far no news. Not sure they care :/ You sure this isn't a config/build issue?

[ryandesign (Ryan Carsten Schmidt)]

No, I am not sure, but I don't see much in the way of configuration in our coreutils Portfile​; we pretty much just build the software its developers have created. If anything in the Portfile looks like it might be causing this, try changing it and see if that solves the problem. If so, you can send us a pull request, or a patch attached to this ticket.
