There is also a special tool for that called metastore:

metastore is a tool to store the metadata of files/directories/links in a file tree to a separate file and to later compare and apply the stored metadata to said file tree. I wrote the tool as a supplement to git which does not store all metadata, making it unsuitable for e.g. storing /etc in a repo. metastore could also be helpful if you want to create a tarball of a file tree and make sure that "everything" (e.g. xattrs, mtime, owner, group) is stored along with the files.

It's also available as Debian package.
