Retaining file permissions with Git

I want to version control my web server as described in Version control for my web server, by creating a git repo out of my

/var/www directory
. My hope was that I would then be able to push web content from our dev server to github, pull it to our production server, and spend the rest of the day at the pool.

Apparently a kink in my plan is that Git won't respect file permissions (I haven't tried it, only reading about it now.) I guess this makes sense in that different boxes are liable to have different user/group setups. But if I wanted to force permissions to propagate, knowing my servers are configured the same, do I have any options? Or is there an easier way to approach what I'm trying to do?

The git-cache-meta mentioned in SO question "git - how to recover the file permissions git thinks the file should be?" is the more staightforward approach.

The idea is to store in a .git_cache_meta file the permissions of the files and directories.
It is a separate file not versioned directly in the Git repo.

That is why the usage for it is:

$ git bundle create mybundle.bdl master; git-cache-meta --store
$ scp mybundle.bdl .git_cache_meta machine2: 
#then on machine2:
$ git init; git pull mybundle.bdl master; git-cache-meta --apply

So you:

  • bundle your repo and save the associated file permissions.
  • copy those two files on the remote server
  • restore the repo there, and apply the permission
