Right; the latest update only ensures that wpa_supplicant is started
after messagebus.

The problem with making network depend on wpa_supplicant is that this
breaks the network-mounted-usr case, because wpa_supplicant is installed
in /usr.  Nothing has been done to work through this yet, there are two
options:

1) Make network-mounted-usr people fend for themselves and don't keep
trying to preserve that use-case from 1992

2) Add the bits to the network service to "suggest" that it start the
supplicant if it's available

You can't make the network service have a hard dependency on the
supplicant because that would result in an error if the user didn't have
the wpa_supplicant package installed, nor can you really make the
sysvinit package depend on wpa_supplicant either, forcing everyone to
install the supplicant even if they don't need it.

Not for everyone, and not as a hard dependency of the network service.
I forget the actual keyword, but try looking around for the advisory
requires option for new LSB initscripts.
