core@localhost /data/config $ git submodule update
/usr/libexec/git-core/git-submodule: line 159: perl: command not found

git-jump, git-sh-setup, git-request-pull, git-am, and git-contacts also appear to use perl and would also break.

With the exception of git-contacts, these are all shell scripts that invoke perl -e without any CPAN modules or anything, so would probably just need the perl bin & libperl

I see this is sort of a dupe from https://github.com/coreos/coreos-vagrant/issues/38

Any chance of supporting it? Kinda sucks to have git not completely functional. I am surprised that git-submodule is actually implemented this way though...

No, we will not be adding Perl just to support a few git commands. We
provide git just to support users that distribute apps/containers/configs
to hosts so development commands aren't needed. Submodule being broken too
is unfortunate but it isn't a commonly used feature.

@marineam can we build git more explicitly without submodule support?

There is an option to disable perl support in the git ebuild but it mostly just limits pulling in extra modules instead of disabling all Perl. It would be good to fix that.

The submodule command works now. They must have removed the Perl dependency at some point.
