Answer 1

There are two kinds of change notices you can suppress (from git 1.7.2).

The first is untracked content which happens when you make changes to your submodule but have not yet committed those. The parent repository notices these and git status reports it accordingly:

modified: book (untracked content)

You can suppress these with :

[submodule "book"]
    path = modules/media
    url = https://user@bitbucket.org/user/repo.git
    ignore = dirty

However, once you commit those changes, the parent repository will once again take notice and report them accordingly:

modified:   book (new commits)

If you want to suppress these too, you need to ignore all changes

[submodule "book"]
    path = book
    url = https://user@bitbucket.org/user/repo.git
    ignore = all
