submodule init: warn about falling back to a local path When a submodule is initialized, the config variable 'submodule.<name>.url' is set depending on the value of the same variable in the .gitmodules file. When the URL indicates to be relative, then the url is computed relative to its default remote. The default remote cannot be determined accurately in all cases, such that it falls back to 'origin'. The 'origin' remote may not exist, though. In that case we give up looking for a suitable remote and we'll just assume it to be a local relative path. This can be confusing to users as there is a lot of guessing involved, which is not obvious to the user. So in the corner case of assuming a local autoritative truth, warn the user to lessen the confusion. This behavior was introduced in 4d6893200 (submodule add: allow relative repository path even when no url is set, 2011-06-06), which shared the code with submodule-init and then ported to C in 3604242f080a (submodule: port init from shell to C, 2016-04-15). In case of submodule-add, this behavior makes sense in some use cases[1], however for submodule-init there does not seem to be an immediate obvious use case to fall back to a local submodule. However there might be, so warn instead of die here. While adding the warning, also clarify the behavior of relative URLs in the documentation.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from http://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git, http://marc.info/?l=git and other archival sites.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
