Git submodule on remote bare

I figured out another solution which looks rather clean to me. Just give git all the info it needs to perform the submodule stuff:

$ cd /path/to/your/git_work_tree
$ git --git-dir=/path/to/your/bare_repo.git --work-tree=. submodule init
$ git --git-dir=/path/to/your/bare_repo.git --work-tree=. submodule update

One possible way might be:

• to setup /var/www/website as a (non-bare) repo
• have your post-receive hook of your bare repo:
  • set GIT_DIR and GIT_WORK_TREE to the non-bare repo at /var/www/website
  • cd /var/ww/website
  • git pull ~/website
  • git submodule update (a bit like in "How do I init/update a git submodule in a working tree after pushing to a bare working directory?")

In other words:
Pull from the bare repo instead of trying to checkout from a bare repo: a non-bare repo should be able then to accommodate the git submodule update step.

An example script may look like

#!/bin/sh

# Get the latest code
cd /path/to/bare/repo

# Set git variables
GIT_WORK_TREE=/var/www/website
GIT_DIR=/var/www/website/.git

# Go to website and pull
cd /var/www/website
git pull /path/to/bare/repo
git submodule update --init --recursive

# Run additional build stuff here
