And another interesting behaviour of git with submodules:

--------------------------------------------------------------------------------
% git status
# On branch master
# Your branch is ahead of 'origin/master' by 8 commits.
#
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#   (commit or discard the untracked or modified content in submodules)
#
#       modified:   modules/tftpd_hpa (modified content)
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       modules/ethz_systems_private/
no changes added to commit (use "git add" and/or "git commit -a")
% git add modules/tftpd_hpa
# On branch master
# Your branch is ahead of 'origin/master' by 8 commits.
#
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#   (commit or discard the untracked or modified content in submodules)
#
#       modified:   modules/tftpd_hpa (modified content)
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       modules/ethz_systems_private/
no changes added to commit (use "git add" and/or "git commit -a")
--------------------------------------------------------------------------------

- Why can modules/tftpd_hpa not be added?
- Why does git checkout not remove modules/ethz_systems_private/,
  when switching from the master to the private branch?
  (the module is only registered in the private branch)

Ok, found out that I changed stuff within modules/tftpd_hpa, instead of
merging from the source.

Imho the git status output is a bit misleading, as I assume that
I can git add stuff that's modified.

Perhaps git add should print a warning / error if I try to add the
changed submodule and not silently ignore it.

Regarding the other problem

I'm still not sure what's the reason for that.

To make such surprises visible is the intent of showing "(modified
content)" here.

Maybe you just overlooked this line in the output of "git status":
"(commit or discard the untracked or modified content in submodules)"

Because there might be stuff in there which is not tracked but you
might hate loosing by switching a branch.
