keyfile plugin initialization and wireless at boot

[Brian DeRocher <brian derocher org>]

Hey everyone,

I'm trying to get my wireless interface to connect at boot.  With nm-applet "Available to all users" is not enabled and i don't understand why.  This is a Debian unstable system with both PolicyKit and polkit installed.

Deciding to skip Dbus / Polkit and all that mess, i though i could place a wireless configuration in /etc/NetworkManager/system-connections/ and it would be loaded at boot.  Some of the forums like Ubuntu and ArchLinux have suggested this.  I tried to follow the settings spec[1] but i'm not sure i got it right.  Using strace ./NetworkManager --no-daemon, i see this system-connections folder is never read!

NM just hangs here after entering state 3.  I've downloaded the NM source code version 0.8-1 and began to insert some debugging statements.  Please excuse my debugging.

I'm still trying to put all the pieces together!  It doesn't look like nm_system_config_interface_init() calls the keyfile plugin init function NM_SYSTEM_CONFIG_INTERFACE_GET_INTERFACE (config)->init (config).  Can someone explain this?

lt-NetworkManager: bcd start loading a plugin
lt-NetworkManager: bcd nm_system_config_interface_get_type()
lt-NetworkManager: bcd nm_system_config_interface_init 1
lt-NetworkManager: bcd nm_system_config_interface_init 2
(missing init function???)
lt-NetworkManager: bcd nm_system_config_interface_get_type()
lt-NetworkManager: bcd nm_system_config_interface_init 5
lt-NetworkManager: Loaded plugin keyfile: (c) 2007 - 2008 Red Hat, Inc.  To report bugs please use the NetworkManager mailing list.

I assume the init function was established in plugin.c here:

G_DEFINE_TYPE_EXTENDED (SCPluginKeyfile, sc_plugin_keyfile, G_TYPE_OBJECT, 0,
				    G_IMPLEMENT_INTERFACE (NM_TYPE_SYSTEM_CONFIG_INTERFACE,
									  system_config_interface_init))

I assume after the init function is called, then read add_connection() and get_connections() can be called.

thanks for your help,
Brian
