Description=NetworkManager Sudo Helper
#
# nm-sudo exists for privilege separation. It allows to run NetworkManager
# without certain capabilities, and ask nm-sudo for special operations
# where more privileges are required.
#
# While nm-sudo has privileges that NetworkManager has not, it does not
# mean that itself should run totally unconstrained. On the contrary, it
# also should only have permissions it requires.
#
# nm-sudo rejects all requests that come from any other than the name
# owner of "org.freedesktop.NetworkManager" (that is, NetworkManager process
# itself). It is thus only an implementation detail and provides no public
# API to the user.
