Re: keyfile plugin initialization and wireless at boot

[Brian DeRocher <brian derocher org>]

Dan,

Thanks for the great tips.

It would really be nice if there was a debug message explaining why the
"Available to all users" box is disabled.  I checked the debian bugs
page [1], but there are no bugs reported... yet.

Yes, plugins=ifupdown,keyfile.  There is no sub-section for [keyfile].

Oh excellent idea, but no.

# strace ./NetworkManager --no-daemon 2>&1 | egrep '(Network-manager|nm-system-settings)' 
open("/etc/NetworkManager/nm-system-settings.conf", O_RDONLY) = 3
open("/etc/NetworkManager/nm-system-settings.conf", O_RDONLY) = 12
open("/etc/NetworkManager/nm-system-settings.conf", O_RDONLY) = 12

Sorry for the ambiguity.  It is probably not a true hang.  I don't know now to speak to it 
with D-Bus directly, except to use qdbus.

You got it...  You get the deluxe bcd version ;)  Keeping in mind i'm looking add_connection and get_connections.
