How to use git commit -s with Ungit?

[chintan-mishra]

When contributing to a repo that enforces DCO then I have to switch to CLI for committing the changes, as Ungit cannot auto-fill the Sign-Off block in the commit message

This might be happening due to alias section in ~/.gitconfig file not getting recognized/parsed. Read more below.

I used this resource to set up git for contributing to repos with DCO.

However, when committing using Ungit, it is expected that the following block will be included

Sgned-off by: FirstName LastName <fname@domain.tld>

But that is not the case. Sign-off doesn't get included.

So, I switched to CLI to test if git is honoring the ~/.gitconfig at all. Here is what I did.

$ git add .
$ git commit

Commits using CLI had the Sign-Off block in the commit message.

How to set up git and Ungit to automatically contain Sign-off block while committing?

Here is the concerned output log obtained from ungit --logGitCommands
