[chef] knife download in chef10

[Dmitrii Golub < >]

Hello

I'd like to migrate to chef 11 from chef 10 and for this I use several links:

https://gist.github.com/hosh/5103957/raw/ebfcec9410edb2c7c99d5da35920ecc63b855eb9/chef-11-migration-draft.txt

http://www.opscode.com/blog/2013/03/12/5106/

http://docs.opscode.com/upgrade_server.html

However I don't fully understand why do we need separate knife.rb just for knife download.

And knife download suprise me with strange behaviour:

knife download -c ~/chef-10/knife.rb transfer/

ERROR: Must specify either chef_repo_path or cookbook_path in Chef config file

knife download / -c chef-10/knife.rb --chef-repo-path repo/ --repo-mode everything

With default knife.rb I receive no errors, however no files were downloaded in specified directory.

mkdir transfer

knife download transfer # no files in transfer folder.

Thanks in advance
