The unlock command needs to copy a file, and it would be great to use this:
	cp --reflink=auto src dst

O(1) overhead on BTRFS. Needs coreutils 7.6; and remember that git-annex
may be used on systems without coreutils..

Only use cp -a if it is supported, falling back to cp -p or plain cp. * cp --reflink=auto is used if supported, and will make git annex unlock much faster on filesystems like btrfs that support copy of write. 2010-11-18 17:48:28 +00:00
