Comment(by dsd):

 Next problem: src/dhcp-manager/nm-dhcp-manager.c dhclient_run() passes the
 -x option to dhclient

 OLPC-2 has dhclient-3.0.5 and OLPC-3 has dhclient-4.0.0

 Fedora had a patch in dhclient-3.0.5 which added a -x option:
 {{{
 +The -x argument enables extended option information to be created in the
 +-s dhclient-script environment, which would allow applications running
 +in that environment to handle options they do not know about in advance -
 +this is a Red Hat extension to support dhcdbd and NetworkManager.
 }}}

 However dhclient-4.0.0 *upstream* added a -x option with totally different
 meaning:
 {{{
 - Added -x option to dhclient, which triggers dhclient processes
   to exit gracefully without releasing leases first
 }}}

 Fedora seem to have silently dropped their version of the -x patch with
 the 4.0.0 release, so running "dhclient -x" is now just a way of telling
 other dhclient's to go away.

 NetworkManager upstream removed the -x option:
 http://svn.gnome.org/viewvc/NetworkManager/trunk/src/dhcp-manager/nm-dhcp-
 manager.c?r1=2674&r2=2681

 So we now need to do the same, to make dhclient actually run when NM
 launches it.

 The #if'd out part was then removed with another change:
 http://svn.gnome.org/viewvc/NetworkManager/trunk/src/dhcp-manager/nm-dhcp-
 manager.c?r1=3215&r2=3401
 (perhaps we need to backport that patch?)
