Since you're copying to a fresh drive anyway, there's no harm in doing it and checking the result. Hard links are an easy case in fact, and trivial to check. Create file A and hard link B to it. Rsync A and B to a different filesystem, using the -H option. Use "ls -i" on the copied files to see that they both have the same inode. That's all a hard link is. > As for ACLs (-A), > what exactly is being handled here and does this work for ALL > Oses concerned - do they follow the same "standard"? WTF? Of course not. I thought we were talking about Linux here. In fact there's been no indication in this thread of anything to the contrary. There is no "standard" for this stuff across OSes (I suppose Posix might be considered a standard but I'd be very careful about relying on it). We're doing low-level system maintenance here.

If you'd said at the beginning that you wanted to move a Vista partition we could have saved ourselves a lot of time. poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
