	Please commit your changes if you modify any files in /etc to git!
	But before that please setup env vars to identify your commits in your ~/.bash_profile:

	export GIT_AUTHOR_NAME='$gecos'
	export GIT_AUTHOR_EMAIL='$email'

	export GIT_COMMITTER_NAME=\${GIT_COMMITTER_NAME:-\$GIT_AUTHOR_NAME}
	export GIT_COMMITTER_EMAIL=\${GIT_COMMITTER_EMAIL:-\$GIT_AUTHOR_EMAIL}

	NOTE: GIT_* vars are imported with sshd so you could setup them where you connect from.

	You may also use git config, but then you must learn to use 'sudo -s' to become root:
	git config --global user.email '$email'
	git config --global user.name '$gecos'
