Ansible roles shared between my different Ansible installations.
To add this as a submodule to an ansible repo:
git submodule add --force https://github.com/tykling/ansible-roles roles/
For reference: Make an alias to update all submodules in a repo:
git config --global alias.updatesub '!git submodule update --init --recursive && git submodule foreach git pull origin master && git submodule foreach "cd \$toplevel && git add \$path" && git commit -m "update all submodules" && git push; git submodule deinit .'
