"git config --list" command not showing complete list, is the configuration incomplete?

Solution 1:

No, a default installation and only specifying user.name and user.email, you will only have those two options list. Take a look at the documentation on where these values are pulled:

If not set explicitly with --file, there are four files where git config will search for configuration options:

$(prefix)/etc/gitconfig

System-wide configuration file.

$XDG_CONFIG_HOME/git/config

Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty, $HOME/.config/git/config will be used. Any single-valued variable set in this file will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create this file if you sometimes use older versions of Git, as support for this file was added fairly recently.

~/.gitconfig

User-specific configuration file. Also called "global" configuration file.

$GIT_DIR/config

Repository specific configuration file.

Take a look at the options. Most have defaults or default behavior that git will take if not specified.

To answer your question, you should have a usable configuration even with those couple specified.
