Also known as "we have our policies for EL6 and we haven't paid any
attention to EL7 to see how things have changed" ... Wonder if they have
read my NM blog article yet ...
Honestly any 'security' people banning wpa_supplicant needs their heads
examined given that is used for 802.1x authentication ... which if they
care about security they should be paying attention to.
As for polkit and dbus ... well they have to be there in EL7 and systemd
relies on these mechanisms.
That said if they're having kittens about NM, polkit, dbus and
wpa_supplicant they probably hate systemd and frankly I'm surprised they
permit EL7 at all ;)
Note that by default a non administrator user cannot change system network
configuration ... bah idiots ...
