git submodule issue

[Daniel-ltw]

Need to work out how to deploy with submodules.

DEBUG [594974e5]    fatal: /usr/libexec/git-core/git-submodule cannot be used without a working tree.

Tried adding the git submodule update command in lib/capistrano/gitcopy.rb

This did not work well and return the following error.
Seems like it requires the actual working tree, which would require all repo files being cloned.

Is there a better way to solve this?

I guess the whole problem lies at how we use --mirror during clone to reduce the disk usage and the time to clone.

Maybe we should not use --mirror?
